  • Resin compositions for light control sheets, and light control sheets prepared from said compositions
    Patent number: 5153260
    Abstract: A resin composition comprising a photo-polymerizable resin and a filler having an average particle size of 0.05-20 .mu.m can be used to be photo-polymerized to yield a light control sheet which may have a thickness of 100 .mu.m or less. Therefore, the resin composition makes it possible to lower the heat generation and curing distorting during a curing step and to make small the necessary amount of the composition for preparing a light control sheet.
