and wherein A.sup.n− is one or more selected from a group consisting of following anions: (a) carbamate orcarbazate; (b) carbonate; (c) formate; (d) bicarbonate; (e) organic monocarbonate; (f) organic poly-carbamate; (g) orthoformate; or (h) organic poly-carbonate. The compound of general formula (I) has at least one of hydroxyalkyl group linked to N atom, i.e., has alkanolamine residue. They can be used as polyurethane foaming agent, and most of them can be used as polystyrene foaming agent or polyvinyl choride foaming agent.

The present invention relates to a decorative material having excellent printability, and the decorative material according to the present invention has an ink-receiving layer having a radially fine sloping structure having a dendritic shape, whereby the absorbing and/or fixing property, i.e., printability, of the ink printed on the ink-receiving layer is improved, and clarity is excellent, so that aesthetic effects are excellent. In addition, since the ink-receiving layer is manufactured through UV curing, it can be directly coated on a substrate layer, and can include various kinds of substrate layers; and since it is manufactured using a solvent-free type resin composition without using an organic solvent, and has an excellent absorbing and/or fixing property with respect to a water soluble ink, it has environmental friendly advantages.

A plasticized PVC formulation for foam extrusion including polyvinyl chloride, at least one plasticizer, at least one nucleating agent and a chemical blowing agent, wherein the plasticized PVC formulation is a dry blend containing 0.5 to 5% by weight of one or more nucleating agents and 0.1 to 3% by weight of the chemical blowing agent, wherein the blowing agent is sodium bicarbonate and the nucleating agent is talcum, and a foam extrusion method using said formulation. The extruded plasticized PVC foam is particularly suitable for rock shield pads used for pipeline protection. The foams are lightweight and require less consumption of materials with comparable properties to corresponding solid articles.

A membrane having permselectivity for perchlorate ion is prepared using certain types of quaternary ammonium salts contained in a polymeric matrix material, which may be plasticized. Such membranes are useful in electrodialysis processes, whereby perchlorate-contaminated aqueous compositions are purified.
