Abstract
An organic glass for automobile is provided which has excellent weatherability, wear-resistance and abrasion-resistance, and which can be mass-produced by a simple and inexpensive process. The organic glass comprises a transparent resin base plate 12 and a hard coat layer 14 formed on at least one surface of the resin base plate. The hard coat layer includes an organic thin film 16 formed by vacuum deposition polymerization.
Claims11
An organic glass for automobile comprising a transparent resin base plate and a hard coat layer directly formed on at least one surface of the resin base plate,
- wherein the hard coat layer includes an organic thin film of polymer formed by vacuum deposition polymerization,
- wherein the organic thin film is constituted by a plurality of layers composed of different compositions, and
- wherein the hardness of the organic thin film varies to become higher stepwise toward the surface thereof.
A process for producing an organic glass for automobile, comprising the steps of:
- providing a transparent resin base plate;
- and
- forming an organic thin film of polymer directly on at least one surface of the resin base plate by a vacuum deposition polymerization, thereby forming a hard coat layer including the organic thin film on at least one surface of the resin base plate,
- wherein the organic thin film is constituted by a plurality of layers composed of different compositions, and
- wherein the hardness of the organic thin film varies to become higher stepwise toward the surface thereof.
