摘要： A base film for a thermal transfer ribbon which is a biaxially oriented polyester film comprising polyethylene-2,6-naphthalene dicarboxylate as a main constitutional element, wherein in a temperature-dimensional change curve under load in a longitudinal direction of the film, the dimensional change from the original length of the film at temperatures of up to 200° C. is 1.0% or less and the dimensional change from the original length of the film at temperatures of up to 230° C. is 3.0% or less. This film may have a coating layer of at least one water-soluble or water-dispersible resin selected from the group consisting of an urethane resin, polyester resin, acrylic resin and vinyl resin-modified polyester resin, on one side thereof. The base film gives a thermal transfer ribbon which has excellent adhesion to a sublimation-type ink layer and excellent printing performance without blurred ink at the time of high-speed printing and without wrinkles formed by friction with a head.

摘要： A method of preparation of an absorbent composite in which an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into an absorbent polymer by polymerization is applied to a substrate, and the monomer is polymerized while the substrate to which the aqueous solution is applied is, on both the sides, held in contact with polymerization-inert surfaces facing each other. A continuous manufacturing method includes the sequential steps of continuously passing a substrate through (1) a region applying to the substrate an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into an absorbent polymer by polymerization, and (2) a region of polymerizing the monomer while maintaining the substrate, on both the sides, in contact with polymerization-inert surfaces facing each other.
