Abstract
The evolution of formaldehyde from shaped cellulose acetayte articles containing methylolated melamine or guanamine polymers is reduced by adding to the solutions from which the cellulose acetate article is regenerated, from 1 to 20% by weight based on the weight of the methylolated polymer of a cyclic urea compound.
