Abstract: The present invention provides an adhesive tape or sheet for application to skin, which is made of an adhesive composition containing an acrylic copolymer having a specific composition and a specific carboxylic acid ester, wherein the acrylic copolymer has a gel fraction adjusted to a specific range. The adhesive tape or sheet for skin of the present invention can be used for first aid adhesive plasters, surgical tapes, large adhesive plasters with a pad, dressing materials and the like.

Abstract: An adhesive sheet for application on skin contains a supporting film, an elastomer film and an adhesive layer laminated in this order, wherein the adhesive layer mainly contains an acrylic polymer and both the adhesive layer and the supporting film contain a component compatible with the acrylic polymer and liquid or pasty at ordinary temperature.

Abstract: A pressure sensitive adhesive sheet which has a moderate adhesive strength, does hardly add physical stimuli to the adherend at the time of peeling and also has such a good processing suitability that the support does not generate swelling deformation by transfer of a liquid component from the adhesive layer. The pressure sensitive adhesive sheet has an adhesive layer formed from a resin composition comprising an acrylic acid ester polymer, a carboxylic acid ester having 16 or more carbon atoms which is compatible with the acrylic acid ester polymer and is liquid or paste at ordinary temperature, and a crosslinking component, and a film supporting the adhesive layer, comprising a polyether urethane resin obtained by allowing a polyol component to react with a polyisocyanate component, wherein the polyol component constituting the urethane resin contains at least one kind of polyether polyol having a polyoxyalkylene backbone represented by a specified repeating unit.

Abstract: A substrate film for an adhesive sheet containing an elastomer resin and a hydrophilic polymer having a tensile modulus of elasticity higher than that of the elastomer resin and/or 8 to 100 parts by weight per 100 parts by weight of the elastomer of inorganic fine particles having an average diameter size of 15 &mgr;n or less are added. An adhesive sheet is formed by providing an adhesive layer on the film. The adhesive sheet prepared using the film containing the hydrophilic polymer as a substrate has sufficient flexibility and sufficient skin follow-up property after its application, while sufficiently satisfying processability in producing the adhesive sheet and handling property in adhering.

Abstract: The present invention is characterized by using an ampholytic latex as binder in a carbonless copying paper prepared by coating on a support a coating composition comprising a stilt agent, a binder and anionic microcapsules containing a color former and drying the composition. The present invention is further characterized by using an association forming polymer in a coating composition in a carbonless copying paper prepared by coating on a support a coating composition containing a stilt agent, a binder mainly composed of a latex and microcapsules containing a color former and drying the coating composition. The present invention is further characterized by using an association forming polymer in a coating composition without using a stilt agent in a carbonless pressure-sensitive copying paper prepared by coating a coating composition comprising a latex and microcapsules containing a color former and drying the composition.

Abstract: Disclosed in this invention are an emulsifier for producing microcapsules, containing as active principle a water-soluble polymer the emulsifier being composed of benzyl (meth)acrylate and/or diisobutylene, styrene and maleic anhydride, microcapsules using the emulsifier, a process for producing the microcapsules, and a non-carbon pressure-sensitive copying paper using the microcapsules.

Abstract: A method for producing microcapsules with an aminoaldehyde polycondensate as a wall material in an aqueous medium containing a water-soluble polymer is disclosed. As the water-soluble polymer, there is used a terpolymer comprising (A) .alpha.-methylstyrene, (B) styrene and (C) maleic anhydride or a quadripolymer comprising (A) .alpha.-methylstyrene, (B) styrene, (C) maleic anhydride and (D) an esterification product of maleic anhydride. This method is especially useful for making pressure-sensitive copy paper.
