Transparent coated resin composite

A transparent coated resin composite comprising:

• a. a substrate of a polymer consisting essentially of methyl methacrylate unit,
• b. a precoating formed on said substrate of at least one silicon compound selected from the group consisting of:
• methacryloxyalkyl-trialkoxysilanes represented by the formula ##STR16## ##STR17## wherein R.sub.1 is an alkylene group having 1 - 6 carbon atoms and R.sub.2 is an alkyl group having 1 - 6 carbon atoms, and hydrolysates thereof;
• aminoalkyl-trialkoxysilanes represented by the formula ##STR18## wherein R.sub.1 and R.sub.2 are as defined above, and hydrolysate thereof;
• vinyltris(alkoxyalkoxy)silanes represented by the formula ##STR19## wherein R.sub.1 and R.sub.2 are as defined above, and hydrolysates thereof;
• and
• vinyltrialkoxysilanes represented by the formula ##STR20## wherein R.sub.2 is as defined above, and hydrolysate thereof;
• and c. an over-coating formed on said precoating of (i) 98 - 50% by weight of at least one silicon compound selected from the group consisting of:
• glycidoxyalkyl-trialkoxysilanes represented by the formula ##STR21## wherein R.sub.1 and R.sub.2 are as defined above, and hydrolysates thereof;
• (3,4-epoxycyclohexyl)alkyl-trialkoxysilanes represented by the formula ##STR22## wherein R.sub.1 and R.sub.2 are as defined above, and hydrolysates thereof;
• N-(aminoalkyl)-aminoalkyl-trialkoxysilanes represented by the formula ##STR23## wherein R.sub.1 and R.sub.2 are as defined above and R.sub.3 is an alkylene group having 1 - 6 carbon atoms, and hydrolysates thereof, and (ii) 2 - 50% by weight of a polymerizable monomer selected from the group consisting of glycidyl acrylate, glycidyl methacrylate, hydroxyethyl acrylate, hydroxyethyl methacrylate, hyroxypropyl acrylate, hydroxypropyl methacrylate, acrylic acid, acrylamide, methacrylic acid, metacrylamide, acrylic salts and methacrylic salts,
• whereby the total thickness of the coating is in the range of 0.0001 - 0.5 mm.
