Radiation curable Michael addition resins having built-in photoinitiators

The liquid, uncrosslinked, UV-curable Michael addition resins and blends of the present invention exhibit performance properties that make them very effective coating materials and these properties can be modified greatly depending upon composition. Michael donors and acceptors can be constructed from Type I and/or Type II photoinitiators and can be included in the coating compositions disclosed to make UV-curable coatings with extraordinary photoreactivity and properties. Resins can be produced that show excellent adhesion to metals, plastics, wood, paper and glass. They exhibit wide ranges of hardness, toughness, flexibility, tensile strength, stain resistance, scratch resistance, impact resistance, solvent resistance, etc. Almost any desired coating performance parameter can be attained by proper selection of raw material building blocks.

Transacetoacetylation with tert-Butyl Acetoacetate: Synthetic Apllications

Reaction of various nucleophiles with tert-butyl acetoacetate (t-BAA, 1a) is shown to be a convenient method for the preparation of a wide variety of acetoacetic acid derivatives.This material can be used to prepare acetoacetates and acetoacetamides from a wide variety of alcohols and amines.Reaction of 1a with an unhindered primary amine such as n-heptylamine under standard conditions gives unwanted byproducts due to the formation of the enamines 24 and 25.Formation of these byproducts can be minimized by dilution and/or altering the mode of addition.
