摘要:
This invention provides a bank note marking agent constituted by a water soluble dye that is adapted to be rendered water insoluble when brought into contact with water or an organic solvent. Alternatively or in addition, the bank note marking agent may be constituted by a marking substance, such as cobalt nitrate, that is adapted to produce a colour when exposed to an oxidizing agent, such as a bleaching agent. The bank note marking agent is preferably adapted for use in a cash in transit box. The dye of this marking agent is preferably constituted by a quaternary dye salt, the preferred salt being a quaternary of pthalo cyanine blue and a suitable nitrogen containing compound such as acetylated pyrrolidone, produced by reacting pyrrolidone with acetic acid in the presence of an acid catalyst to produce the acetylated pyrrolidone, whereafter the acetylated pyrrolidone is reacted with the pthalo cyanine blue in the presence of a pH reducing agent such a methylethanolamine to produce the salt.

Thermoplatic resin compositions suitable for laser welding are discribed in which black colorants are added. These colorants constitute amine salts of anthraquinone dyes. Additional dyes, coloring agents, and a variety of other materials may be added. These compositions demonstrate outstanding mechanical and chemical properties once laser-welded.

摘要:
Disclosed is a method for grafting a polymer onto the surface of a carbonate material with carboxyl, amine, and/or hydroxyl functions on its surface. Said material is placed in suspension in a solution including the polymer to be grafted, which has a carboxyl, amine, and/or hydroxyl function, said solution also being comprised of a polymer solvent. A process which stimulates the dehydration into a carboxyl function of an amine and/or hydroxyl function is then performed, and the polymer is grafted onto the carbonate material using ester or amide links. The invention can be used in the cathode or naode of an electrochemical generator, in polymer materials with low polar properties, in ink, and also as a conductive coating on flexible plastic used as an electrical contact, as electromagnetic shielding, or as static protection.
