Title:
OPTICAL ELEMENTS THAT INCLUDE CURABLE THIN FILM- FORMING COMPOSITIONS CONTAINING BLOCKED ISOCYANATE ADHESION PROMOTORS
Document Type and Number:
Japanese Patent JP2014139695
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical element made of a substrate and a curable thin film-forming composition applied to at least a portion of the substrate to form a coating on the substrate.SOLUTION: The curable thin film-forming composition comprises: i) a resinous material comprising a monomer, oligomer and/or polymer containing reactive functional groups; ii) a curing agent having two or more reactive functional groups that are reactive with functional groups in the resinous material of i); and iii) a material different from i) and ii), comprising a blocked isocyanate group blocked with a blocking agent capable of deblocking at a low temperature. The material of iii) is present in the curable thin film-forming composition at least in an amount sufficient to improve adhesion between the curable thin film-forming composition and the substrate and/or a superposed coating, when being compared to a substantially identical optical element that does not comprise the material of iii) in the curable thin film-forming composition.
