PRIMER COMPOSITION FOR OPTICAL ARTICLE, AND PHOTOCHROMIC LAMINATE CONTAINING CURED BODY OF THE PRIMER COMPOSITION FOR OPTICAL ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a primer composition for optical article capable of obtaining a photochromic laminate which has high surface hardness, forms a laminated structure which is hardly scratched, has excellent adhesion, and further has photochromic characteristics.SOLUTION: There are provided a primer composition for optical article, which contains (1) a water dispersible urethane resin having Vickers hardness after drying of 10-25, and (2) a reactive compound having at least one reactive group selected from the group consisting of a radical polymerizable group, a silanol group and a group forming a silanol group by hydrolysis in the molecule; and further a photochromic laminate having an optical substrate, a primer coat layer, and a photochromic layer laminated in this order, where the primer coat layer is a cured body of the primer composition for optical article.SELECTED DRAWING: None
