  • Publication number: 20190292413
    Abstract: To provide an adhesive composition for stationery capable of forming an adhesive layer having a good glue-cutting property while suppressing an increase in manufacturing cost and a laminate using the adhesive composition. Carbon fibers having an aspect ratio in the range of 6 to 30 were compounded in an adhesive component, such as an acrylic resin, to give an adhesive composition for stationery. The adhesive composition is applied onto one surface of a base material 1, such as a plastic film or paper, to form an adhesive layer 2, and thus a laminate 10, such as a glue tape, a seal, and a label, is obtained.

  • Patent number: 5091297
    Abstract: A silver halide color photographic material comprising a support having thereon at least one silver halide red-sensitive emulsion layer containing at least one cyan coupler represented by formula (I) or (II) ##STR1## wherein Za represents ##STR2## Zb represents ##STR3## Zc represents ##STR4## Y represents a hydrogen atom or a blocking group; X represents a hydrogen atom or a group which releases upon a reaction with an oxidation product or an aromatic primary amine color developing agent; R.sub.11 represents a group which is substantially not released upon reaction with an oxidation product of an aromatic primary amine color developing agent; R.sub.12 represents a hydrogen atom or a substitutent; or R.sub.11, or R.sub.12 or X may form a dimer, oligomer or polymer.The silver halide color photographic material containing the novel cyan coupler is excellent in color reproducibility and image preservability.
