Description

Composition, resin composition, and method for producing composite Technical Field The present invention relates to a composition, a resin composition, and a method for producing a composite. Background Light-softening compositions softened by light irradiation are used in various applications. For example, patent document 1 discloses an image forming apparatus including a recording member having a light-softening resin layer made of a light-softening resin. Technical literature of the prior art Patent literature Patent document 1 Japanese patent laid-open No. 11-190883 Disclosure of Invention Technical problem to be solved by the invention The main object of the present invention is to provide a resin composition which has high elasticity and can exhibit tackiness by light irradiation. Means for solving the technical problems One aspect of the present invention relates to a resin composition containing a complex of a compound having a carboxyl group and a disulfide bond and a phenoxy resin, and a photo radical initiator. Another aspect of the present invention relates to a composition comprising a compound having a carboxyl group and a disulfide bond, a phenoxy resin, and a condensing agent. Another aspect of the present invention relates to a method for producing a composite, wherein a compound having a carboxyl group and a disulfide bond is reacted with a phenoxy resin in the presence of a condensing agent. Effects of the invention According to the present invention, a resin composition having high elasticity and capable of exhibiting tackiness by light irradiation can be provided. Further, according to the present invention, a method for producing a composite exhibiting light softening properties can be provided. Detailed Description Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to the following embodiments. In the present specification, "photo-softening property" means a property that, by light irradiation, viscosity is reduced, elastic modulus is reduced, loss tangent (tan δ) is increased, hardness is reduced, and the like. In the present specification, the term "process" refers to not only an independent process but also a process that can achieve the intended function of another process when it cannot be clearly distinguished from the other process. In the present specification, a numerical range expressed by "-" means a range including numerical values before and after "-" as a minimum value and a maximum value, respectively. In the numerical ranges described in stages in the present specification, the upper limit value or the lower limit value of the numerical range in a certain stage may be replaced with the upper limit value or the lower limit value of the numerical range in another stage. In the numerical ranges described in the present specification, the upper limit value or the lower limit value of the numerical range may be replaced with the value shown in the embodiment. The upper limit and the lower limit described individually can be arbitrarily combined. In the present specification, the content of each component in the composition indicates the total amount of a plurality of substances present in the composition unless otherwise specified, in the case where a plurality of substances corresponding to each component are present in the composition. Also, unless otherwise indicated, the exemplified materials may be used alone or in combination of 2 or more. "A or B" may include either or both of A and B. The "(meth) acrylate" refers to at least one of an acrylate and a methacrylate corresponding thereto. The same applies to other similar expressions such as "(meth) acryl". The resin composition according to the present embodiment contains a complex of a compound having a carboxyl group and a disulfide bond and a phenoxy resin, and a photo radical initiator. The complex according to the present embodiment is a reactant of a compound having a carboxyl group and a disulfide bond (hereinafter, sometimes referred to as "(a) component") and a phenoxy resin (hereinafter, sometimes referred to as "(B) component"). (A) The carboxyl group of the component (a) and the hydroxyl group of the component (B) can react to form an ester bond. The complex according to the present embodiment is presumed to have disulfide bonds derived from the component (a) and ester bonds formed by the reaction of the component (a) and the component (B). The resin composition according to the present embodiment exhibits high elasticity by containing such a complex, and when the resin composition is irradiated with light, disulfide bonds in the complex are decomposed (cracked) to generate sulfur radicals. At this time, if a photo radical initiator is present in the resin composition, sulfur radicals react with the photo radical initiator, and the sulfur radicals are blocked by the photo radical initiator. Thus, the viscosity of the resin composition can be re
