Abstract:
An ultraviolet absorbing plate produced by providing on a substrate an ultraviolet absorbing layer formed from an ultraviolet absorbing material having an amide bond and an Si--O bond, wherein said ultraviolet absorbing material comprises a reaction product of (a) an aminosilane compound of formula (1) or a hydrolysate thereof with (b) an ultraviolet absorber having in its molecules a carboxyl group so as to form an amide bond derived from the aminosilane compound or a hydrolysate thereof,said formula (1) being represented by ##STR9##wherein R.sup.1 is a C.sub.1 -C.sub.10 alkylene group or a divalent group of the formula --(CH2).sub.m --NH-- in which m is an integer of 1-4, R.sup.2 are the same or different and each is selected from the group consisting of a hydrogen atom, a hydroxyl group, a halogen atom, a C.sub.1 -C.sub.10 alkyl group and a C.sub.1 -C.sub.10 alkoxy group, provided that at least one of R.sup.2 is an alkoxy group, and n is an integer of 0 or greater.
