An optical recording medium having a thin film layer consisting mainly of an organic dye and formed on a substrate and characterized in that said thin film layer consists mainly of a dye mixture comprising a polymethine dye (A) and an aza-annulene dye (B).

Optical recording medium

A photosensitive resin composition which comprises (1) an ethylenically unsaturated compound which can be addition polymerized to form a high molecular compound, said addition polymerization being initiated by a free radical and chain-propagating, (2) a 2-polycyclic aryl-4,5-diphenylimidazolyl dimer wherein the polycyclic aryl group at the 2-position comprises at least two benzene rings condensed each other and (3) a heterocyclic mercaptan compound, said photosensitive resin composition being excellent in having a high photopolymerization initiation potency.

Photosensitive resin containing a combination of diphenyl-imiazolyl

A hydroxyl terminated copolyester which is basically constituted with ethylene glycol and terephthalic acid is formulated into a heat curable powder coating composition by mixing with specific plural silicone compounds. The resultant paint film is excellent in flatness and free from leveling faults and has superior properties.
