Description

Allergen reducing agent, allergen reducing liquid, allergen reducing paint, and masterbatch for molding synthetic resin Technical Field The present invention relates to an allergen reducing agent, an allergen reducing liquid, an allergen-reducing coating material, and a masterbatch for molding synthetic resins. Background In recent years, various allergic diseases such as atopic dermatitis, bronchial asthma, allergic rhinitis have become a problem. The allergic disease is mainly caused by an increase in the living space of allergens such as allergens (Der 1, der 2) of house dust mites (house dust mite) existing in a large amount in house dust, and cryptomeria fortunei pollen allergens (Cryj 1, cryj 2) floating in the air in a large amount mainly in spring. The allergen of house dust mites is not house dust mites per se, but carcasses and faeces of house dust mites become allergens, so that allergic diseases cannot be fundamentally solved even if house dust mites are repelled. Cryj1 and Cryj2, which are cryptomeria pollen allergens, are glycoproteins having a molecular weight of about 40kDa and a molecular weight of about 37kDa, respectively, and these cryptomeria pollen allergens are recognized as foreign substances outside organisms when they adhere to nasal mucosa or the like, and cause inflammatory reactions. Therefore, there is a need for a technique for removing an allergen from a living space, or for inactivating an allergen by denaturing the allergen or the like. Patent document 1 discloses allergen-removing particles comprising a vinyl polymer having an H-type carboxyl group and a crosslinked structure in an amount of 0.5 to 12 mmol/g. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2009-160563 Disclosure of Invention Problems to be solved by the invention However, the allergen-removing particles disclosed in patent document 1 are insufficient in allergen-processing ability (allergen-reducing effect), and an allergen-reducing agent exhibiting an excellent allergen-reducing effect is required. The allergen-removing particles of patent document 1 can be incorporated into various products to produce allergen-removing products. Allergen-removing articles are generally in contact with a person's hand during use thereof, or may cause friction with other articles, or the like. Therefore, there is also a problem that the allergen-removing particles contained in the allergen-removing product fall off, and the allergen-reducing effect is reduced in a short time. The invention provides an allergen reducing agent which can reduce the falling off from a substrate and exert excellent allergen reducing effect for a long time, and an allergen reducing liquid, an allergen reducing coating material and a masterbatch for synthetic resin molding using the allergen reducing agent. Means for solving the problems The allergen reducing agent of the present invention comprises an allergen reducing compound having an alkoxysilyl structure represented by formula (1) or a silanol structure represented by formula (2) in a molecule and having a structure containing an acidic functional group or an acid anhydride group thereof, [ Chemical formula 1] (Wherein R 1 in formula (1) is alkyl, and each of formulae (1) and (2) is a bond arm and represents a single bond.) The allergen-reducing liquid of the present invention comprises the above-mentioned allergen-reducing agent and a solvent. The allergen-reducing coating material of the present invention comprises the above allergen-reducing agent, a solvent and a binder resin. The masterbatch for molding a synthetic resin of the present invention comprises the allergen-reducing agent and a synthetic resin. ADVANTAGEOUS EFFECTS OF INVENTION The allergen-reducing agent of the present invention contains, as an active ingredient, an allergen-reducing compound having an alkoxysilyl structure or a silanol structure in the molecule and having a structure containing an acidic functional group or an acid anhydride group thereof, and therefore exhibits an excellent allergen-reducing effect. The alkoxysilyl structure or silanol structure of the allergen-reducing agent of the present invention forms a strong bond with the substrate, and thus reduces the detachment from the substrate, and can provide the substrate with an excellent allergen-reducing effect over a long period of time.
