  The invention relates to a process for preparing polyisocyanate/polysilicic acid based resins wherein one or more polyisocyanates is/are reacted with water glass optionally in the presence of one or more additives and/or auxiliary agents conventionally used in the preparation of polyisocyanate/polysilicic acid based resins. According to the invention at least 5 % by weight of the polyisocyanate is replaced by a polyisocyanate in which at least 30 % of the isocyanate groups are blocked, and at least 50 % of the blocked isocyanate groups are blocked with (a) a compound comprising structural units with two mobile hydrogens of acidic character and derivatives thereof in which one of the mobile hydrogens is replaced by a substituent X, wherein X represents halo, hydrocarbyl, hydrocarbyl-oxy, hydrocarbyl-carbonyl or hydrocarbyl-oxy-carbonyl group or a combined group formed from two or more of these groups, (b) an unsaturated oxime of formula (I) wherein R10 and R11 each represent a hydrocarbyl group or one of them may also represent hydrogen, or R10 and R11 form, together with the adjacent carbon atom, a cyclic hydrocarbyl group, with the proviso that at least one of R10 and R11 comprises a nonaromatic unsaturated carbon-carbon bond; (c) a compound comprising a single isocyanate-reactive -OH group bound to a carbon atom and at least one nonaromatic unsaturated carbon-carbon bond or with any combination thereof. The invention also relates to the new blocked polyisocyanates usable in the above process.
