Abstract
The present invention relates to an additive composition for abatement of free aldehydes, particularly formaldehyde, or removing the same in the air, comprising—a polymer of acetoacetyl functional ethylenically unsaturated monomer, which contains at least 70 wt % of at least one acetoacetyl functional ethylenically unsaturated monomer, and 0 to 30 wt % of at least one ethylenically unsaturated monomer other than the acetoacetyl functional ethylenically unsaturated monomer, based on the total weight of all monomer(s), and—optionally, at least one amine, and to an interior coating composition comprising the additive composition.
