ANTIFOGGING ARTICLE AND MANUFACTURING METHOD THEREOF, BASE LAYER FORMING COMPOSITION, AND ARTICLE FOR TRANSPORTATION APPARATUS

摘要

An antifogging article having an antifogging film excellent in antifogging property and in durability, an article for transportation apparatus provided with the antifogging article, and a base layer forming composition with sufficiently long pot life used for obtaining the antifogging article are provided. An antifogging article has a substrate, and an antifogging film on the substrate having a base layer made of a base material with low water absorbing property, and a water absorbing layer made of a water absorbing material having a water absorbing property higher than that of the base material, and the base material is obtained by using a composition containing (A) a raw material component of a first cured resin, (B) a silane-based coupling agent having a functional group other than an amino group having reactivity with the (A) component and a hydrolyzable group, and (C) tetraalkoxysilane and/or a polymer thereof in a prescribed ratio.

主权项

1. An antifogging article having a substrate and an antifogging film on a surface of at least a part of the substrate, wherein:
the antifogging film has, in order from the substrate side, a base layer made of a base material with low water absorbing property, and a water absorbing layer made of a water absorbing material having a water absorbing property higher than that of the base material; and the base material is obtained by using a base layer forming composition comprising the following (A) to (C) components: (A) 100 parts by mass of a raw material component of a first cured resin; (B) 60 to 200 parts by mass of a silane-based coupling agent having a functional group other than an amino group having reactivity with the (A) component and a hydrolyzable group; and (C) 15 to 50 parts by mass, by oxide conversion, of tetraalkoxysilane and/or a polymer thereof.
