Abstract: The present invention provides a resin composition for paint, which contains a thermo-decomposition type foaming agent and polyester resin for paint, a laminate obtainable by applying said composition to a substrate, an article containing said laminate, and a method for recovering a substrate from a laminate comprising heating said laminate. And the paint in the laminate obtainable from said resin composition and the substrate is adhered firmly to the substrate until recycled and the paint layer can easily be peeled off from the substrate by heating the laminate. The resulting substrate can be reused.

Abstract: A trisazo compound represented by the following formula (I) in the free acid form: ##STR1## wherein Q is an phenyl or naphthyl group both of which may be unsubstituted or substituted; one of the A and B is hydroxy group and the other is amino group; K is 1 or 2; and one of m and n is 1 and the other is 0; a method for dyeing fiber materials, paper or leather by using the trisazo compounds and an ink containing the trisazo compounds, and the trisazo compound is excellent in solubility, and good in storage stability and free from clogging of nozzle caused by deposition. The ink using the trisazo compound gives a deep black-colored image excellent in clarity, water-durability and durability to light.

Abstract: A trisazo compound represented by the following formula (1) in the free acid form: ##STR1## wherein Q' is phenylene group, Q.sup.2 is phenyl or naphtyl group, one of the A and B is a hydroxy group and the other is an amino group, K is 1 or 2, one of m and n is 1 and the other is 0, X and Y independently of one another are each --OR.sup.1, --SR.sup.2, --NR.sup.3 R.sup.4 or ##STR2## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of one another are each a hydrogen atom, an alkyl, phenyl or naphthyl group; r is 1 or 2; and Z is --CH.sub.2 --, --O--, --SO.sub.2 -- or --NR.sup.5 -- wherein R.sup.5 is a hydrogen atom or C.sub.1 -C.sub.4 alkyl group;a method for dyeing fiber material, paper or leather by using the trisazo compound;and an ink which contains the trisazo compound and which is excellent in storage stability and can give a clear black printed image having excellent water resistance and light fastness.

Abstract: A bisazo compound represented by the formula (I) in the free acid form, ##STR1## wherein D is unsubstituted or substituted phenyl or naphthyl; A and B are independently unsubstituted or substituted phenylene or naphthylene; R is hydrogen or unsubstituted or substituted lower alkyl; X is aromatic amino residue or aliphatic amino residue; arid Y is a group represented by the formula, ##STR2## wherein R.sup.1 is hydrogen or unsubstituted or substituted alkyl, W.sub.0 is unsubstituted or substituted alkylene; and Z is vinyl or --CH.sub.2 CH.sub.2 Z.sub.1, in which Z.sub.1 is a group capable of being split by the action of an alkali; is a reactive dye useful for dyeing or printing fiber materials having hydroxy groups and/or amide groups to brown or violet color, and can provide dyed or printed products with superior fastness properties and dyeing properties such as build-up property.
