The laminate has a resin substrate and a composite layer thereon. The composite layer contains an inorganic compound and a cellulose fiber exhibiting an average fiber diameter of not less than 2 nm and not more than 200 nm. The laminate has a flexible substrate which exhibits superior gas-barrier capability as well as enhanced mechanical strength and heat-resistance and is suitably applicable to a variety of display substrates.

Laminate and production method thereof

A method of manufacturing a micro-particle dispersion having a hydrophobic protective colloid comprising the steps of: (a) dispensing micro-particles in a hydrophilic dispersant to form a hydrophilic micro-particle dispersion having the hydrophilic dispersant as a protective colloid, and (b) adding a dispersant to the hydrophilic micro-particle dispersion, the dispersant having a functional group capable of ion bonding with a hydrophilic group of the hydrophilic dispersant.

Micro-particle dispersion having hydrophobic protective colloid and method of manufacture thereof, photosensitive emulsion and method of manufacturing thereof, and silver salt photohermographic dry imaging material utilizing the same

A silver salt photothermographic dry imaging material wherein said material has photographic speeds () and () determined based on the predetermined conditions and the photographic speed () is not more than 1/10 of the photographic speed (), and the coefficient of determination value Rof the linear regression line is 0.998-1.000, which is obtained from the predetermined density points having a* and b* arranged in two-dimensional coordinates in which a* is used as the abscicca and b* is used as the coordinate of the CIE 1976 (L*a*b*) color space, b* of the intersection point of the linear regression line with the ordinate is &#x2212;5-5, and gradient (a*/b*) is 0.7-2.5.

Silver salt photothermographic dry imaging material

A silver salt photothermographic dry imaging material wherein said material has photographic speeds (1) and (2) determined based on the predetermined conditions and the photographic speed (2) is not more than 1/10 of the photographic speed (1), and the coefficient of determination value Rof the linear regression line is 0.998&#x2013;1.000, which is obtained from the predetermined density points having a* and b* arranged in two-dimensional coordinates in which a* is used as the abscissa and b* is used as the coordinate of the CIE 1076 (L*a*b*) color space, b* of the intersection point of the linear regression line with the ordinate is &#x2212;5&#x2013;5, and gradient (a*/b*) is 0.7&#x2013;2.5.

A photothermographic imaging material containing a support having thereon photosensitive silver halide grains, light-insensitive organic silver salt grains, a reducing agent for silver ions and polymer, wherein and average particle size of the photosensitive silver halide grains is 0.005 to 0.1 &#x3bc;m, and the polymer dissolves both in water and in an organic solvent.
