  • Photocurable primer composition and coating method by use of the same
    Patent number: 6844029
    Abstract: A photocurable primer composition containing (A) an acrylic resin having through an urethane linkage a polymerizable unsaturated group on its side chain and containing the polymerizable unsaturated group in an amount of 0.2 to 2.0 mol/kg in a solid content of the resin (A), (B) an urethane (meth)acrylate oligomer containing at least one polymerizable unsaturated group in one molecule, and (E) a photopolymerization initiator, and a coating method.

  • Repair coating method
    Patent number: 6821569
    Abstract: A repair coating method which comprises coating a photocurable processing composition (I) onto a damaged area of a substrate to form a processed layer, followed by coating a colored base coating composition (II) onto the processed layer to form a colored base layer, and coating a photocurable clear composition (III) onto the colored base layer to form a clear layer.

  • Reproduced image product and a method of forming a reproduced image layer
    Patent number: 6149754
    Abstract: A method of forming reproduced in images on the surface of cured coating, the method including the steps of treating a surface of a cured coating with an organic solvent which does not dissolve the cured coating, but slightly dissolves a reproduced image layer and has a solubility parameter of about 7.5 to about 8.2, superposing, over the cured coating, a copying sheet which comprises a copy support having a reproduced image layer formed thereon to bring the reproduced image layer of the copying sheet into contact with the organic solvent-treated surface of cured coating, heat-transferring the reproduced image to the treated surface of cured coating, releasing the copy support to provide a transfer product on the cured coating, and forming a clear coating on the surface of the transfer product.
