Molding sheet for forming hard coat layer
09556317 · 2017-01-31 · ·

The object of the present invention is to provide a molding sheet for forming a hard coat layer having an excellent shelf life or tracking ability to the mold in a semi-cured state, and having an excellent abrasion resistance after being cured completely, a molded body having a hard coat layer, and a method for manufacturing the same. The present invention relates to a molding sheet for forming a hard coat layer, comprising a layer consisted of a semi-cured material of a composition comprising: a) an organosilicon compound, b) a ultraviolet ray curable-compound, and c) a silanol condensation catalyst on the substrate, and to a molded body using the same.

OPTICAL ARTICLE COMPRISING A DOUBLE-LAYER ABRASION AND SCRATCH RESISTANT COATING AND METHOD FOR PRODUCTION THEREOF
20170003420 · 2017-01-05 ·

The invention relates to an optical article comprising a substrate coated with an abrasion and scratch resistant coating composed of a lower layer and an upper layer that do adhere to each other, the upper layer and the lower layer being layers of cured upper and lower layer compositions, said upper layer composition comprising at least one organosilane, or a hydrolyzate thereof, of formula R.sub.nY.sub.mSi(X).sub.4nm and at least one compound, or a hydrolyzate thereof, of formula M(Z).sub.x, the following ratio being lower than 2.3:
