A curable resin composition for forming anti-fogging abrasion-resistant coating essentially consisting of:
- 20-90 parts by weight of the hydrolysate of at least one compound selected from the group consisting of compounds of the formulae ##STR7## wherein R.sup.1 is an alkylene group having 2-6 carbon atoms, R.sup.2 is an alkylene group having 2-4 carbon atoms, R.sup.3 is an alkyl group having 1-4 carbon atoms, R.sup.4 is either OR.sup.3 or an alkyl group having 1-3 carbon atoms, and X is either of hydrogen and methyl;
- 8- 10% by weight of at least one polymerizable compound selected from the group consisting of compounds of the formulae ##STR8## wherein R.sup.5 is an alkylene group having 2-3 carbon atoms, R.sup.6 is either of hydrogen and an alkyl group having 1-3 carbon atoms, X is either of hydrogen and methyl, n is an integer of 2-20 and m is an integer of 4-20, and said groups R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 may be staight chained or branched, whereby the total of said hydrolysate and said polymerizable compounds is 100% by weight;
- and 0.01-10% based on the total weight of the above compounds of at least one curing catalyst selected from the group consisting of hydrolysis catalysts for said silicon compounds and radical polymerization initiators.
