The problem addressed by the present invention is to provide an antifogging coating film having excellent antifogging property, antifogging persistence, persistence of appearance, and elution resistance. The coating film according to the present invention contains a metal oxide (A) and a hydrophilic compound (B); the height of the eluate by a coating film surface elution test is 1.0 m or less; this test is carried out by placing 10 L of deionized water on the coating film, allowing the film to stand for 24 hours in a 23 C., 50% RH environment, measuring the eluate height of 20 locations selected randomly within a 10 cm.sup.2 range on the coating film surface, and determining the maximum height; and the water contact angle measured after subjecting the coating film to a moisture resistance test by exposure for 24 hours in an 85 C., 85% RH environment followed by standing for one hour in a 23 C., 50% RH environment, is less than 40. Preferably, the elution level per coating film unit volume by a coating film total elution test is 40 mg/cm.sup.3 or less, and this test is carried out by immersing the coating film in 23 C. deionized water for 24 hours, then measuring the weight of the coating film eluate recovered from the deionized water.

The invention pertains generally to a shelf-stable polyurethane HFO-blown two-component polyurethane foam composition which includes controlling the ratio of tin-containing catalyst(s) to potassium-containing catalyst(s).
