The present invention is directed to a polymeric isocyanate modified epoxy blocked sulfonic acid ester as a catalyst for the crosslinking of polymers having hydroxyl, carboxyl, and amide functional groups with a crosslinking agent and resin compositions containing the same. More particularly, the present invention is directed to a polymeric isocyanate modified epoxy blocked sulfonic acid ester with a molecular weight of about 1000 preferably prepared from a sulfonic acid, an epoxy resin and a mono- or di-isocyanate and resin compositions containing the polymeric isocyanate modified epoxy blocked sulfonic acid ester catalyst. The catalyst when used in the crosslinking or curing of hydroxyl, carboxyl or amide containing polymers with an acid catalyzed amino-formaldehyde crosslinking agent, such as hexamethoxymethylmelamine ("HMMA"), produced polymeric film coatings which have superior hardness, impact resistance, adhesion, improved blister resistance, salt spray characteristics and flexibility.

摘要:
A method and compound for detecting and identifying and/or quantifying a deaminase enzymatic activity of a microorganism, according to which an inoculum suspected of containing a microorganism with a deaminase activity is brought into contact with a culture medium for microorganisms, wherein the culture medium comprises at least one detection agent for demonstrating, by forming a colored product with a revealing agent, a deaminase enzymatic activity; said detection agent being an L-amino acid of following general formula (I): in which R represents an organic radical containing a cyclic ring, said cyclic ring being substituted with 1 to 3 substituents that are identical or different and each of which limits the diffusion in the culture medium of the &agr;-keto acid produced by the deamination of the at least one detection agent, as compared to where each of said substituents is not present.
