Abstract:
A water resistant ink composition comprising:(I) 10 parts by weight of a water-soluble dye compound or an organic pigment compound or both;(II) 2 to 60 parts by weight of an organosilicon compound (C) obtained by hydrolyzing a mixture comprising(A) 100 parts by weight of a hydrolyzable silane obtained by reacting (i) an aminated organic group-bearing hydrolyzable silane of the general formula:YR.sup.1.sub.m SiR.sup.2.sub.3-m (1)wherein R.sup.1 is an unsubstituted or substituted monovalent hydrocarbon group having 1 to 8 carbons, R.sup.2 is an alkoxy or acyloxy group having 1 to 4 carbons, Y is an aminated organic group, and m is 0 or 1, with (ii) an organic monoepoxy alcohol in an amount corresponding to from 0.01 to 20 moles of epoxy groups per mole of amino groups in the hydrolyzable silane, or a partial hydrolyzate thereof, and(B) 5 to 200 parts by weight of a hydrolyzable silane of the general formula:R.sup.3.sub.n SiR.sup.4.sub.4-n (2)wherein R.sup.3 is an unsubstituted or a non-nitrogenous substituted monovalent hydrocarbon group having 1 to 8 carbons, R.sup.4 is an alkoxy or acyloxy group having 1 to 4 carbons, and n is 0, 1 or 2, or a partial hydrolyzate thereof; and(III) 30 to 10,000 parts by weight of water.
