Abstract: An autonomous travel-type cleaner includes a housing, a drive unit for moving the housing, an incoming call detector that detects whether or not there is an incoming call to a communication terminal, a person detector that detects whether or not a person is present within a first range, an incoming call notification unit (for example, a light source and a speaker) for notifying of presence of an incoming call, and a controller. The controller controls a notification operation of the incoming call notification unit based on a detection result of the person detector and a detection result of the incoming call detector.

Abstract: Provided is a recording method for image formation on a recording medium by application thereon of an ink containing a water-soluble dye having an anionic group or a cationic group in the molecule: the recording medium comprising a substance having an ionic group counter to the anionic or cationic group of the water-soluble dye and having molecular weight of not higher than 1,000, and a polymeric substance having molecular weight of not lower than 2,000.

Abstract: An ink-jet printing process using an ink containing a dye having an ionicity. The process includes the steps of: providing a cloth containing (a) a substance having an ionicity opposite to the ionicity of the dye and a molecular weight of from 100 to 700, or a nonionic surfactant having a molecular weight of from 100 to 700 and an H.L.B. of from 7 to 15, and (b) a polymeric substance having an ionicity opposite to the ionicity of the dye and a molecular weight of from 2,000 to 200,000; printing on the cloth with the ink; washing the cloth after printing; and drying the cloth.

Abstract: Disclosed herein is an ink-jet printing cloth suitable for use in printing with inks each containing a dye having an ionicity, wherein a substance not having the same ionicity as that of the dye and having a molecular weight lower than 1,000, and a polymeric substance having an ionicity opposite to that of the dye and a molecular weight higher than 2,000 are applied to the cloth.

Abstract: Disclosed herein is a printing medium, comprising a liquid-absorbent base material, an ink-receiving layer provided on the base material, which comprises a pigment, a binder and a cationic substance, and a surface layer provided on the ink-receiving layer composed principally of cationic ultrafine particles as inorganic particles.

Abstract: A composition comprising a water-soluble cationic group-containing high-molecular compound (P1) derived from the reaction of (A) epichlorohydrin and a dialkyl or dialkanol amine, or (B) a glycidyl group-terminated hydrophilic oligomer and a diamine, dialkylamine or dialkanolamine; optionally, a high-molecular compound (P2) having a condensable functional group in a side chain such as alkylolacrylamide-bearing high-molecular compound (E) or hydrolyzable trialkylsilyl group-containing acrylic ester high-molecular compound (F); and a poly(meth)acrylate (P3) is coated onto a substrate and cured by ultraviolet radiation to form a printing medium.

Abstract: A process for producing a printing medium is disclosed wherein a composition is applied to a substrate and cured by heat treatment, said composition comprising a water soluble cationic polymer (P1) selected from the group consisting of polymer (A) obtained by the addition polymerization of epichlorohydrin and a dialkylamine or dialkanolamine; polymer (B) derived from the addition polymerization of a glycidyl groups-terminated hydrophilic oligomer and an asymmetric diamine, dialkylamine or dialkanolamine; acrylic polymer (C) with a cationized hydroxyl group-containing molecular side chain; and polyvinyl alcohol (D) with a cationized hydroxyl group-containing molecular chain; and a condensable functional group-containing polymer (P2) selected from the group consisting of alkylolacrylamide copolymer and a hydrolyzable trialkylsilyl group-containing copolymer.
