摘要:
A process for producing a silver halide photographic material comprising a polyester support having thereon at least one light-sensitive layer and at least one undercoat layer is described, wherein the undercoat layer is provided by coating a solution containing gelatin for an undercoating binder having a calcium ion (Ca.sup.++) content of from 10 to 2,500 ppm based on dry gelatin.

An erasable diazotype intermediate assembly comprising a translucent paper base, a rubber-like polymeric intervening barrier layer and a sensitizing layer consisting of a water soluble cellulose derivative, a cross linking resin and the diazo sensitizing chemicals.
摘要:
Cellulose materials such as paper and card stocks are provided in a generally transparent or so-called transparentized form while substantially maintaining the initial strength and stiffness of the pretreated stock. A generally opaque stock is treated with a solventless resin system which is cured by actinic radiation in order to thereby transparentize the stock without subjecting it to lengthy and relatively severe wetting conditions.
摘要:
A transparent cellulosic paper is produced by coating or impregnating a cellulosic paper with an organic solvent solution containing a compound having a weight-average molecular weight of 200 to 2,000 and having at least two isocyanate groups in a molecule or with an organic solvent solution containing, in addition to said compound, at least one compound selected from the group consisting of an aliphatic monohydric alcohol having 6 to 18 carbon atoms and a nonionic surface active agent to the polyethylene glycol type having one hydroxyl group in a molecule, the ratio OH/NCO in the solution being less than 1; removing said organic solvent; and allowing the coated or impregnated paper to harden by aging.
