Abstract: A photoelectric conversion apparatus includes photoelectric conversion elements that each include a photoelectric conversion unit disposed on a side of a first surface of a semiconductor layer, and in which light enters from a side of a second surface opposite to the first surface, a first element isolation portion that extends in the semiconductor layer from the first surface toward the second surface, and a second element isolation portion that extends in the semiconductor layer from the second surface toward the first surface and comes into contact with the first element isolation portion. The coated portion is in contact with the second element isolation portion.

Abstract: A resin which has excellent adhesion to nonpolar substrates, is nontacky, and has satisfactory solubility in aromatic or nonaromatic solvents and satisfactory compatibility with other resins. The resin is a modified polyolefin resin having a weight-average molecular weight of 15,000 to 150,000 obtained by modifying a polyolefin resin by grafting thereto (A) an unsaturated polycarboxylic acid or a derivative thereof and (B) a (meth)acrylic ester represented by a specific general formula, the contents of (A) and (B) in the modified polyolefin resin being 0.1 to 20 wt. % and 0.1 to 30 wt. %, respectively.

Abstract: A novel chlorine-free modified polyolefin resin composition with excellent adherence to nonpolar substrates, excellent solubility in solvents, excellent compatibility with other resins, and without tack after painting and drying is obtainable by graft modifying a mixed resin having 40 to 99 parts by weight of polyolefin resin (A) and 1 to 60 parts by weight of ethylenic compound-unsaturated carboxylic acid copolymer (B) that contains 0.1 to 50% by weight of unsaturated carboxylic acid derivative, with unsaturated carboxylic acid derivative and/or its anhydride (C), the modified polyolefin resin composition having weight average molecular weight of 20,000 to 150 000 and the grafting weight of (C) being 0.1 to 20% by weight.

Abstract: Disclosed is a polyamide-modified polyolefin composition obtainable by heating to react modified polyolefin with weight average molecular weight of not less than 5,000 to not more than 150,000, graft modified so as the content of unsaturated carboxylic acid anhydride to become 0.1 to 20 wt. % and polyamide with number average molecular weight of not less than 3,000 to not more than 30,000 at a particular weight ratio. The purpose is to provide a novel chlorine-free modified polyolefin with excellent adherence to polyolefin substrates, with no tack, and also with excellent cohesion.

Abstract: Disclosed is a novel chlorine-free modified polyolefin composition with excellent adherence to polyolefin substrates, with excellent solventresistance, oil resistance and weather resistance, with no tack, and also with excellentcohesion, obtainable by using 0.5 to 15% (by weight) of maleic anhydride and 0.1 to 7.5% (by weight) of styrenic monomer to polypropylene, eyhylene-propylene copolymer or ethylene-propylene-buten copolymer, and by graft polymerizing so as the weight ratio of maleic anhydride to styrenic monomer to become not less than 2 to not more than 5.
