摘要:
Disclosed is Printing paper which incorporates a sheet substrate and a dye-receiving layer wherein the dye-receiving layer contains a vinylphenolic resin and a dyeable resin or contains a polymer of a vinylphenolic resin, a butyral resin and a poly-functional isocyanate. The printing paper is used in thermal sublimation transfer recording and gives an image with improved storing characteristics in terms of the light resistance, dark fading resistance, sebum resistance, plasticizer resistance, etc.
摘要:
A printing paper for use in sublimation-type thermal transfer recording includes a sheet-like base and a dye receiving layer disposed thereon. The dye receiving layer is composed of a copolymer of substituted or unsubstituted phenoxypolyethylene glycol acrylate or substituted or unsubstituted phenoxypolyethylene glycol methacrylate and another monomer. The substituted or unsubstituted phenoxypolyethylene glycol acrylate or the substituted or unsubstituted phenoxypolyethylene glycol methacrylate is of a proportion of at least 50 weight % of the copolymer.

摘要:
Using a thermoplastic norbornene type plastic as a material for the magnetic disc substrate, a magnetic disc substrate having a small deformation and a high modulus of elasticity is prepared. By optimizing the thickness of the substrate, the resonance frequency of the magnetic disc can be elevated to a level higher than the servo band. As a result, a magnetic disc substrate can form a servo mark having a high positional precision, and can carry out tracking with high precision.

摘要:
A thermal transfer recording material for use in a recording apparatus in which the thermal transfer recording material is introduced into a transfer section having a porous structure by an effect of capillarity, subjected to a state transformation by heating, and then transferred to a recording medium disposed in an opposed relation to the transfer section, comprising:a dye represented by the general formula (I): ##STR1## where R.sup.1 and R.sup.2 are individually a substituted or unsubstituted alkyl or alkenyl group, or a cycloalkyl group, and when both R.sup.1 and R.sup.2 are unsubstituted alkyl groups, at least one of R.sup.1 and R.sup.2 is a branched alkyl group.
