Abstract
Solutions of maleimide resins comprising a mixture of bismaleimides and low but solubilizing amounts of maleamic acids are provided at high solids levels, e.g. at least about 50%. Such solutions which comprise common solvents such as acetone, methyl ethyl ketone and toluene are useful in preparing laminates based on bismaleimide resins.
