摘要:
This invention is an inkjet recording sheet having a high gloss cast coating recording layer containing a pigment and a binder comprising mainly polyvinyl alcohol on a support having air permeability, wherein the pigment is a mixture comprising alumina (A) and silica (B) having an average particle diameter of 100˜500 nm, blended in the proportion of A:B=95:5˜50:50 in terms of weight ratio. The silica (B) is preferably a silica to which cationic properties have been imparted, and the alumina (A) is preferably γ-alumina. Due to this, the gloss of a silver halide photograph together with excellent ink absorption properties and print density can be obtained.
摘要:
A method of manufacturing an inkjet recording cast-coated paper wherein a coating solution containing a pigment and a binder resin is supplied to a base paper, a treatment solution having the function of solidifying the binder resin is supplied to the coating layer while it is still wet in order to solidify the coating layer, and the wet, solidified coating layer is brought into pressure contact with the mirror surface of a heated drum and dried to obtain a cast-coated layer. According to this invention, the treatment solution is supplied by the double pond method wherein the roll is enclosed by the base paper so as to bring the wet coating layer into contact, and ponds of treatment solution are formed both before and after the coating layer comes into contact with the roll.

摘要:
This invention is an inkjet recording medium formed by providing a recording layer comprising γ-alumina having an average particle diameter of 8 μm or less as pigment, and a urethane resin having a glass transition temperature of 10° C.-50° C. together with polyvinyl alcohol as a binder, on a support having air permeability. The surface image clarity of the recording layer is 20% or more. The recording layer can be provided by the cast coating method.
摘要:
An inkjet recording medium having a gloss comparable to that of a silver halide photograph is disclosed. This inkjet recording medium is prepared by coating a recording layer containing alumina and polyvinyl alcohol on a support having air permeability, applying a treatment solution containing a borate and a water-soluble magnesium salt while the recording layer is still wet, pressing the recording layer in contact with a heated mirror surface while the recording layer is still wet, and drying.
摘要:
A composite for radiography is disclosed which essentially consists of a) a silver halide photographic light-sensitive material comprising a transparent support and at least one light-sensitive silver halide emulsion layer provided on each side of the support, b) fluorescent screen A having a 80 kVp X-ray energy absorption of 40% or more and c) fluorescent screen B having a 80 kVp X-ray energy absorption of 50% or more and the absorption more than fluorescent screen A, the material being sandwiched between the screens A and B in such a manner that emulsion layer A is in close contact with screen A and emulsion layer B is in close contact with screen B, wherein the slope of the straight portion in the characteristic curve of emulsion layer A is less than that of emulsion layer B and emulsion layers A and B of the silver halide photographic light-sensitive material have sensitivity on an exposed side that an exposure necessary to give a density of the minimum density +0.5 is 0.027 to 0.040 lux.multidot.second.
