Abstract: A method for cutting a specific layer of a synthetic resin laminated film comprising at least two kinds of closely laminated synthetic resin material film layers having spectral absorption characteristics different from each other, which comprisesplacing the focus of a laser ray having a wavelength that enables the laser ray to be absorbed by the specific film layer to be cut and transmitted through the film layer not to be cut, on said specific film layer directly or through the other transmitting film layer; andmoving the focus of the laser ray on the plane of said specific film layer, moving said specific film layer on the plane of said specific film layer under a stationary laser focus, or forcing the focus and said specific film layer, respectively, to move in conjunction, keeping the focus on the plane of said specific film layer, whereby said specific film layer only will be selectively cut along the predetermined line or curve.

Abstract: Photosensitive compositions which contain as a photosensitive resin prepared by the condensation of the co-condensated novolak resin of the mixture of phenols such as in a combination of tert-butyl (or tert-octyl) phenol and phenol and/or cresol and formaldehyde, with o-quinonediazido sulfonic (or carboxylic) acid or contain said novolak resin as an additive for a photosensitive o-quinonediazido compound are discosed.

Abstract: Disclosed is an imaging light-sensitive material which comprises a transparent substrate, [I] a polyamide layer containing an alcohol-soluble polyamide as the major component and having a thickness of from 2 to 11 microns and [II] a light-sensitive layer having a thickness of from 0.5 to 5 microns.

Abstract: Disclosed is a liquid composition for treating photosensitive laminates having an alcohol-soluble polyamide layer, which comprises 12 to 70 parts by weight of an aromatic neutral salt, 0.01 to 10 parts by weight of an alkali, 1 to 15 parts by weight of an alcohol and 84 to 100 parts by weight of water.

Abstract: A polyolefin film is coated with an undercoat consisting essentially of a mixture of (a) polyvinylidene chloride or a copolymer thereof containing at least 88 percent by weight of vinylidene chloride monomer units and (b) a chlorinated polypropylene or a graft polymer thereof; at the weight ratio of a/b in the range between 99/1 and 90/10, and a topcoat consisting essentially of a vinylidene chloride copolymer containing not more than 88 percent by weight of vinylidene chloride monomer units.

Abstract: A polyolefin film is coated with an undercoat of a mixture of (a) graft copolymer of chlorinated polypropylene to which is grafted a chlorinated vinyl monomer or a styrene monomer and (b) acrylonitrile-butadiene rubber, and a top coat of vinylidine chloride copolymer.
