Article treated to be hydrophilic

TLDR: In this article, a polycarbonate resin plate is coated with a coating solution prepared by blending a curable phosphazene compound with methyl isobutyl ketone as a solvent and p-chlorobenzophenone as an initiator, cured by irraidiating with high pressure mercury lamp light.

Abstract: PURPOSE:To obtain the title article useful for window glass, having a static contact angle of surface to water of >=a specific value by hydrophilic treatment, excellent non-fogging properties, transparency and scratching properties and high surface hardness, comprising a polymer compound containing P=N skeleton. CONSTITUTION:A polycarbonate resin plate, etc., is coated with a coating solution prepared by blending a curable phosphazene compound shown by formula I (R is group shown by formula II) with methyl isobutyl ketone as a solvent and p-chlorobenzophenone as a photopolymerization initiator, cured by irraidiating with high-pressure mercury lamp light, the laminate is immersed in 20 % aqueous solution of NaOH (25 deg.C) for 20 minutes, washed with water, dried to give the objective hydrophilic article having the surface comprising a polymer compound containing-P=N-skeleton, >=40 deg. static contact angle of surface to water and non-fogging properties, transparency and scratching properties.
