Abstract

PURPOSE:To obtain a photographic support having considerably improved hiding power without producing microgrit by coating titanium dioxide with at least one kind of specified amido compound in a production stage. CONSTITUTION:At least one side of a paper or synthetic paper substrate is coated with a resin composition consisting essentially of titanium dioxide and resin to obtain resin coated photographic paper. At this time, titanium dioxide coated with at least one kind of amido compound represented by formula I or II in a production stage is used as the titanium dioxide. In the formula I, each of R1 and R2 is 1-20C optionally substituted alkyl. In the formula II, R3 is 2-20C optionally substituted alkylene. The preferred amount of the amido compound used to treat the surface of titanium dioxide is 0.01-2wt%, especially 0.1-1.0wt% of the amount of the titanium dioxide. The surfaces of titanium dioxide particles are preferably coated with the amido compound by spraying a soln. of the amido compound in a low b.p. nonaqueous solvent on the particles or mixing the soln. with the particles.

DETAILED DESCRIPTION OF THE INVENTION (A> Industrial Application Field The present invention relates to a support for photographic paper, and more specifically, a resin composition containing titanium dioxide is coated on at least one surface of a paper or synthetic paper substrate. This invention relates to resin-coated paper coated by elution extrusion in the form of a film.

(B) Prior Art The essential structure of resin-coated paper for photography is already known. For example, as disclosed in U.S. Pat. No. 3,501,298, both sides of a paper base are coated with resin, and the emulsion-coated side is In this method, the resin layer contains a titanium dioxide pigment, a blue pigment, and a fluorescent whitening agent.

In the first place, the method of incorporating pigments into polyolefin resins is to prepare a so-called masterbatch in which pigments are contained in the resin at a high concentration in advance, and then dilute and mix them with a diluent resin to the desired ratio, or to use the pigments in a polyolefin resin. It is usual to prepare and use a so-called compound in which a desired composition ratio is contained in a resin from the beginning.

However, especially when preparing a masterbatch or compound by ordinary melt-kneading using a Banbury mixer, kneader, etc., relatively coarse pigment particles are not dispersed into a fine state but are dispersed as they are in the resin. There is a tendency for undispersed pigment particles to be present in the masterbatch or compound. As a result, the resin surface of a photographic resin-coated paper in which at least one surface of the paper or synthetic paper substrate is coated with a resin composition comprising a pigment and a resin produced using the mask-batch or the compound. Microgrit, which is minute foreign matter or minute particles, will be generated on top.
