Abstract:
A laminate includes a first area formed by applying a first composition and a second area formed by applying a second composition on a surface of the first area, and a difference between refractive indexes of the first area and the second area is 0.5 or greater, and the first areas and the second areas are alternately laminated.
Abstract:
A gap embedding composition used for embedding a patterned gap formed between photosensitive resin film portions on a semiconductor substrate surface, the gap embedding composition, having a hydrolysis condensate having an average molecular weight of 3,000 to 50,000 derived from an alkoxysilane raw material including at least alkyltrialkoxysilane and an ether compound having a total carbon atom of from 7 to 9 and/or an alkyl alcohol compound having a total carbon atom of from 6 to 9, as a solvent.
Abstract:
An optical member set which has a first optical member formed by curing a composition of curable resins, and a second optical member which is covered by the first optical member, in which the contact angle with water on a surface, which comes into contact with a first optical member, of the second optical member is 70 to 97° and the contact angle with the water on a surface of the opposite side to the side, which comes into contact with the second optical member, of the first optical member is 80 to 115°.
