Setting composition and ink, paint and adhesive containing the same composition

Method for removing resin

Method for the removal of an applied film having a resin containing a unit represented by the following formula (1)

Method of removal of applied film

A process for removing a multiple coating film or an adhering substance and a layer of a cured adhesive agent which comprises a step of contacting a coated article (A) containing a multiple coating film having a lower coating layer formed on a substrate and an upper coating layer formed on the lower coating layer or an adhering substance (B) being allowed to adhere to a substrate by a layer of a cured adhesive agent with a mixture (C) comprising an acidic compound (a) and water as an essential component, the lower coating layer containing a cured binder resin having a chemical structure shown by the following chemical formula (1)

Process for removing multiple coating film or adhering substance from substrate

A process for forming a cured paint film from a paint containing, as a binder, a resin containing a carbonyl group, or a resin, or a resin mixture containing a carbonyl group and a carboxyl group or a paint containing, as a binder, a resin containing a resin or a resin mixture containing a group which forms a carboxyl group in the subsequent contact step with a hydrazine compound or polyhydrazide compound. The uncured paint film, which contains a carbonyl group, or a carbonyl group and a carboxyl group or a group that forms a carboxyl group, is subjected to a step of curing the paint film by allowing the uncured paint film to contact with a hydrazine compound or a polyhydrazide compound.

Processing for forming cured paint film

A resinous composition for two-liquid type water paint crosslinkable at the normal temperature which has a long pot life and which is superior in properties such as hardness, gloss, solvent resistance and water resistance is disclosed. A resinous composition comprises: (A) a colloidal dispersion or emulsion obtained by copolymerizing a monomer mixture comprising a carbonyl group-containing unsaturated monomer, carboxyl group-containing unsaturated monomer and other unsaturated monomers to form a copolymer, neutralizing the copolymer with an alkali, dissolving or emulsifying it into water, and adjusting the pH to above 7; and (B) an easily water soluble dihydrazide compound having from 1 to 5 carbon atoms.

Resinous composition for two liquid type water paint crosslinkable at

A resinous composition for water paint crosslinkable at the normal temperature is provided, which is suitable for painting interiors and exteriors of buildings, bridges, vehicles and et al, which is non-odored, as well as which has advantages in safe and hygienic aspects. A resinous composition for a water paint, which is obtained by blending an aqueous dispersion of a carbonyl group-containing copolymer (A) with a carbonyl group-containing aqueous polyurethane resin (B) at the ratio of 100 parts by weight of solids in (A) to 5.about.150 parts by weight of (B), and then adding as a crosslinking agent a hydrazide compound having at least 2 hydrazide groups per one molecule (C) at the ratio of 0.01.about.2 moles of (C) to 1 mole of carbonyl group contained in the said (A) and (B) components, wherein the said polyurethane resin (B) being obtained by copolymerizing an unsaturated polyurethane resin obtained by the reaction of a diisocyanate compound with a polyol having a number average molecular weight of 60.about.10,000, a carboxyl group-containing diol and a hydroxyl group-containing ethylenic unsaturated monomer with a carboxyl group-containing ethylene unsaturated monomer.
