  • Patent number: 7820286
    Abstract: A coating composition capable of forming a curable coating layer having a sufficient dyeability on a resin substrate and improving adhesion after dyeing between the resin substrate and the curable coating layer, and a resin product having optical permeability applied with the curable coating layer by the composition are provided. The coating composition contains an ingredient (A): a hydrolyzate of an organosilane with the content of a bifunctional organosilane of from 50 to 100% by weight, an ingredient (B): colloid particles of metal oxide, and an ingredient (C): a solvent.
    Type: Grant

  • Patent number: 7183004
    Abstract: A coating composition having a high adhesion which is capable of forming a cured film on a resin substrate by using one liquid. There is further provided a coating composition which is capable of obtaining a cured film having favorable dyability which is effective to a resin substrate having a poor dyability and, also, capable of suppressing a whitening phenomenon, and a resin product having the coating composition. The coating composition contains (A) component: a polycarbonate diol, (B) component: colloidal particles of a metal oxide, (C) component: a hydrolysate of an organosilane and (D) component: a solvent. The polycarbonate diol functions as an adhesion promoter and is effective in forming the cured film on the resin formed product without applying the pretreatment liquid. Further, since the polycarbonate diol functions also as a dyability imparting agent, the dying performance thereof can be adjusted according to the amount thereof.

  • Patent number: 6177138
    Abstract: There is provided a coating composition for the formation of a hard coat having sufficient adhesivity to acrylic resin molded articles. A hard coat obtained by dispersing and dissolving a (partial) hydrolyzate of an organofunctional silane and colloidal silica in a benzyl alcohol solvent is coated on an acrylic resin molded article produced by cell casting or continuous casting to obtain an abrasion-resistant molded article.
