An absorbent article comprises a liquid-permeable surface sheet, a liquid-impermeable leak-proof sheet and an absorbent layer disposed between the two sheets, said leak-proof sheet having on the outside surface a composite comprising a hydrophobic polymer having a glass transition temperature of zero degree centigrade or lower and foamed beads of a polymer. It is improved in the anti-slipping property, the leak-proof property and the permeability to moisture.

The present invention provides a method for producing a coated paper, including steps of coating a base paper coated with an aqueous solution of a water-soluble polymer with a coating liquid containing at least a pigment and an adhesive to produce a coated paper, and calendering the coated paper having a moisture content of not more than 5.5% by weight. The present invention also provides a method for producing a coated paper, including steps of coating a base paper having a moisture content of not more than 4% by weight with a coating liquid containing at least a pigment and an adhesive to produce a coated paper, and calendering the coated paper having a moisture content of not more than 5.5% by weight.
摘要:
The invention relates to disintegrating particles formed by agglomerating primary particles at least part of which are insoluble in water, wherein the agglomeration of the disintegrating particles is disintegrated in an aqueous solution containing a water-soluble salt by lowering the concentration of the water-soluble salt. The invention also relates to a cleanser or detergent composition that includes the disintegrating particles, a water-soluble salt at a concentration lower than its saturated solubility, a surfactant and water. The composition has excellent physical (mechanical) cleanability and stability with time and gives users a pleasant feeling upon use. The composition does not cause damage to and itch on the skin because the disintegrating particles are disintegrated during cleansing and rinsing, and it is extremely good in rinsability.
摘要:
The present invention provides a surface treatment agent for paper such as a coating base paper. The surface treatment agent contains a cationic group-containing copolymer produced by polymerizing a specific vinyl monomer and a specific cationic group-containing vinyl monomer at a specific ratio.
摘要:
A liquid-absorbent composite comprises (a) a water-absorbent polymer, (b) a water-insoluble inorganic material and (c) a water-insoluble hydrophilic fibrous material at a weight ratio between (a), (b) and (c) in the range of 100:5-1200:5-1200. It is very useful as the absorbent component for a sanitary napkin and a medical pad.
摘要:
A dry developer composition for electrophotography is disclosed capable of retaining a positive charge and comprises a binder resin and a colorant, the binder resin being a polymer obtained by polymerizing, in a suspension, (A) 98 to 99.95 parts by weight of a hydrophobic copolymerizable monomer and (B) 0.05 to 2.0 parts by weight of a tertiary amino group-containing copolymerizable monomer having the formula (1): ##STR1## in which R1 is hydrogen or methyl, X is --COO-- or --CONH--, R2 and R3 are each an alkyl having 1 to 4 carbon atoms or an aryl and n is an integer of 1 to 4, in the presence of (C) 0.5 to 5.0 parts by weight of an azonitrile polymerization initiator.
