Abstract
Three-dimensional substrates having on at least one surface a coating formed of a polyurethane polyene composition obtained by reacting from about 10 to about 50 parts by weight of a polyene in the presence of about 100 parts by weight of a hydrophilic polyurethane resin. Transparent substrates are rendered antifogging by such coatings. The drag resistance of boat hulls may be decreased by a coating of the compositions and marine growth thereon may be inhibited by incorporating substances such as mercurous acetate in the coating.
