RESIN SUBSTRATE HAVING A HARD COAT FILM AND PRODUCTION METHOD OF RESIN SUBSTRATE WITH A HARD COAT FILM

WIPO Patent Application WO/2012/086656

A1

Disclosed is a structure comprising a silicon-based hard coat layer provided on a resin substrate with a primer layer therebetween; said structure improves scratch resistance and weather resistance properties such as weather-resistant adhesion and weather crack resistance. The production method of the resin substrate with a hard coat film involves: a step for coating at least one surface of the resin substrate with a primer layer-forming composition containing an acrylic polymer as the main component and for drying said composition to form a primer layer; a step for subjecting the surface of the aforementioned primer layer to corona discharge treatment; a step for performing silane coupling agent treatment by coating the surface of the primer layer, which has been subjected to corona discharge treatment, with a silane coupling agent composition containing a silane coupling agent as the main component and drying said composition; and a step for forming a hard coat layer by coating the surface of the aforementioned primer layer, which has undergone the aforementioned corona discharge treatment and silane coupling agent treatment, with a hard coat layer-forming composition containing organopolysiloxane as a main component and curing said composition.
