Abstract: A coating composition characterized in that it contains a compound obtained by reacting an amino resin with an organic polyphosphonic acid.

Abstract: A water base coating composition having a solid content of from 50 to 80 wt % and having a binder component dissolved or dispersed in a solvent mixture comprising water and a hydrophilic organic solvent, said binder component comprising from 30 to 95 wt % of a polyester resin obtained from an aromatic polybasic carboxylic acid or its acid anhydride and a polyhydric alcohol and having a hydroxyl value of from 100 to 280 and an acid value of from 0 to 15, and from 70 to 5 wt % of a melamine resin and/or a benzoguanamine resin.

Abstract: A molding process for producing a molded plastic product with a resin coating layer formed on its surface, which comprises electrostatically coating a powdery resin composition on the inner surface of a mold, filling and molding a plastic material in the mold to form a molded plastic product, and plasticizing, under compression, said powdery resin composition by the heat of the filled plastic material and/or by the heat for molding the filled plastic material, to form a resin coating layer securely bonded to the surface of the molded plastic product by anchor effect.

Abstract: A jet printing ink composition comprises 2 to 60 wt.% of a binder precursor of an alkoxysilane having the formula R.sub.4-n Si(OH).sub.n (n=0 to 2; and R represents a C.sub.1 -C.sub.4 alkoxy group, methoxyethoxy, ethoxyethoxy or phenoxy group) or an oligomer thereof; and 25 to 95 wt.% of a solvent for said alkoxysilane or oligomer thereof; 0.001 to 5 wt.% of a solvent soluble acid; and 0.1 to 8 wt.% of a solvent soluble dyestuff, if necessary, further comprises up to 2 wt.% of a solvent soluble inert silicone oil for inhibiting blotting and up to 3 wt.% of an electroconductive agent.

Abstract: An ink composition for ink jet recording consisting essentially of a water-soluble wetting agent, water, a water-soluble dye and an oxygen absorber.

Abstract: Disclosed is a jet ink composition which comprises an aqueous jet ink containing a water-soluble dye, a wetting agent and water as main components and, incorporated therein, a water-soluble ultraviolet absorbing agent as well as a metal salt, when necessary.

Abstract: A method of ink jet printing by injecting ink through a fine nozzle and electrostatically deflecting the ink particles to print a symbol corresponding to a predetermined matrix, the improvement wherein said ink comprises a non-aqueous ink comprising a coloring agent and a mixture of formamide and an aliphatic monohydric alcohol.

Abstract: This invention relates to a method for coating inner faces of metal pipes of a small diameter which comprises feeding a stream of a powdery resin at a rate of 2 to 10 m/sec into a metal pipe of a small diameter preheated at a temperature higher by 20.degree. to 70.degree.C. than the melting or softening point of said powdery resin so that the concentration of said powdery resin or a mixture of said powdery resin and a carrier is 5 to 40% by volume.
