Abstract: PROBLEM TO BE SOLVED: To provide a heat-storing gel which has a relatively large heat absorp tion capacity, is soft, and does not cause excessive cooling when used as an antipyretic agent for human bodies. SOLUTION: This gel is prepared by dispersing microcapsules comprising shells and a latent-heat-storing agent contained therein in a gel formed from an aqueous solution of a water-soluble polymer (e.g. carboxymethyl cellulose) and sealing the resultant product into a bag formed from a soft synthetic resin sheet. A latent-heat-storing agent having a phase transition point of about 5-20 deg.C is used.

Abstract: PROBLEM TO BE SOLVED: To provide an ink holder more excellent than a conventional one because the absorbing capacity thereof is not lowered even after the drying of ink and ink can be re-absorbed from an introducing part even if ink overflows to be perfectly absorbed and capable of being adjusted in ink absorbing speed in a vertical direction by forming a slit to the ink holder vertically or driving a pin in the ink holder vertically. SOLUTION: An ink holder consists of an ink passing material and the ink absorbing material brought into contact therewith and both of the ink passing material and the ink absorbing material comprise soft polyurethane foam and the ink passing material is composed of a material obtained by adding a surfactant to the soft polyurethane foam produced by using a foamable raw material containing a polyol, an isocyanate, a catalyst and a foaming agent and the ink absorbing material is obtained by thermally compressing the soft polyurethane foam by 2-20 times by a hot press and adding a surfactant to the compressed foam.

Abstract: PROBLEM TO BE SOLVED: To delay and upgrade discoloration properties of an urethane foam by setting all color difference changes before and after an ultraviolet test, an Nox test, a heat test and a wet heat test under predetermined conditions of a cushioning material to specific values or less. SOLUTION: A film is laminated on one surface of a soft polyurethane foam to constitute the cushioning material. A numeric value for evaluating discoloration properties of the material is set to 7 or less for all color difference changes before and after an ultraviolet test at the time of conducting an ultraviolet ray illumination for 9 hours by using a carbon arc 1 lamp by a fade meter an Nox test at the time of exposure of a sample for two hours with 500 ppm Nox gas, a heat test at the time of heating a sample for two hours at 120 deg.C, and a wt heat test at the time of heating a sample for five days under conditions of 70 deg.C and 95% R.H.

Abstract: PROBLEM TO BE SOLVED: To obtain a flexible polyurethane foam developing no scorch even if incorporated with no discoloration-proofing agent, and having further excellent nonyellowability, by reaction between a polyol and an aliphatic or alicyclic polyisocyanate in the presence of a combination of specific two kinds of catalyst. SOLUTION: This flexible polyurethane foam is obtained by subjecting a system described below to reaction. The system is composed of (A) a polyol (e.g. polyether polyol), (B) an aliphatic or alicyclic polyisocyanate (pref. 3- isocyanatomethyl 3,5,5-trimethylhexyl isocyanate), (C) a tin-based catalyst as metallocatalyst (e.g. stannous octoate) and (D) a tertiary amine catalyst as amine-based catalyst (pref. dimethylaminoethyl ether or triethylenediamine) [and a conventional amidino group-bearing amine, pref. 1,8-diazabicyclo(5,4,0) undecene-7], (E) water, (F) a foam stabilizer, and (G) other auxiliary(ies).

Abstract: PROBLEM TO BE SOLVED: To provide a flexible polyurethane foam which indicates a weak acidity in the wet state.
SOLUTION: The weak-acidic flexible polyurethane foam is formed by foaming a raw material blend containing a weak acidic component. This weak-acidic flexible polyurethane foam is manufactured by using a polymer component containing as weak acidic components sodium acrylate and/or a polymer therefrom. This foam indicates a weak acidity in the wet state because of the weak acidity of sodium acrylate.
