COMPOUND TITANATE COATING FILM AND COMPOUND TITANATE FILM-COATED RESIN SUBSTRATE

摘要

PPROBLEM TO BE SOLVED: To obtain a compound titanate coating film and a compound titanate film-coated resin substrate excellent in coating film hardness and adhesiveness. PSOLUTION: The coating film is obtained by coating a substrate with an aqueous medium suspension liquid containing a metal alkoxide and a flake-like titanate prepared by treating a layered titanate with an acid and allowing an organic basic compound to induce interlayer swelling or exfoliating, and then heat treating the coating to crosslink and harden the metal alkoxide. The layered titanate is preferably expressed by the formula of ASBx/SBMSBy/SBDSBz/SBTiSB2-(y+z)/SBOSB4/SB, wherein A and M represent different metals each having a valence of 1 to 3, D represents a defective portion of Ti, x is a positive real number satisfying 0x1, and y and z are 0 or positive real numbers satisfying 0y+z1.
