    • The invention relates to a sol-gel coating material containing (A) an acrylate copolymer solution containing at least one acrylate copolymer (A1); (B) a parent varnish which can be prepared by hydrolysis and condensation of at least one hydrolysable silane (B1) of the general formula (I) SiR4, in which the variable R=hydrolysable groups, hydroxy groups and non-hydrolysable groups, provided that there should be at least one, preferably two, hydrolysable groups; and (C) an additive solution containing c1) at least one ethylenically unsaturated compound containing at least one epoxide group; c2) at least one silane (B1) with at least one non-hydrolysable group R presenting at least one epoxide group; and c3) at least one adduct of at least one silane (B1) with at least one non-hydrolysable group R presenting at least one amino group and at least one cyclic ethylenically unsaturated dicarboxylic acid anhydride. The invention also relates to the use of said sol-gel coating material for producing scratchproof sol-gel coatings.
    • 本发明涉及含有(A)含有至少一种丙烯酸酯共聚物(A1)的丙烯酸酯共聚物溶液的溶胶 - 凝胶涂料; (B)可以通过水解和缩合通式(I)SiR 4的至少一种可水解硅烷(B1)制备的母体清漆,其中可变的R =可水解基团,羟基和不可水解的基团提供 应该有至少一个,优选两个可水解基团; 和(C)含有c1)至少一种含有至少一个环氧基团的烯属不饱和化合物的添加剂溶液; c2)至少一种具有至少一个具有至少一个环氧基团的不可水解基团R的硅烷(B1); 和c3)至少一种至少一种硅烷(B1)与至少一种具有至少一个氨基的至少一种不可水解基团R和至少一种环状烯键式不饱和二羧酸酐的加合物。 本发明还涉及所述溶胶 - 凝胶涂层材料用于制备防刮溶胶 - 凝胶涂层的用途。
