A crosslinking composition includes a compound having at least two functional groups that are each independently represented by Chemical Structure (I):

##STR00001##

X is an oxygen, sulfur, or nitrogen; R.sup.1 is an alkyl group, an aryl group, or an alkylaryl group; R.sup.2, R.sup.3, and R.sup.4 are each independently an alkyl group, an aryl group, an alkylaryl group, or a hydrogen; R.sup.5 is an alkyl group, an aryl group, an alkylaryl group, or a hydrogen; z is 0 when X is oxygen or sulfur and z is 1 when X is nitrogen; and when a double bond is formed between a carbon atom bonded to R.sup.3 and an adjacent nitrogen, m is 0, and when a single bond is formed between the carbon atom bonded to R.sup.3 and the adjacent nitrogen, m is 1.

A foam composition comprises a recycled polyvinyl butyral in an amount from 5 wt % to 70 wt %; an ethylene-ester copolymer in an amount from 10 wt % to 70 wt %; a foaming agent in an amount from 0.5 wt % to 3.5 wt %; a peroxide crosslinking agent in an amount from 0.5 wt % to 3.0 wt %; and a hydrazide crosslinking agent in an amount from 0.1 wt % to 2.5 wt %, based on a total weight of the foam composition. A foam produced from the foam composition can avoid emitting an unpleasant odor of aldehydes, and the foam also has good mechanical properties and good resilience.

An example of an ultraviolet (UV) light fusing agent for three-dimensional (3D) printing includes a vehicle and a multi-functional antioxidant and UV light absorber dispersed in the vehicle. The vehicle includes water and a water miscible or water soluble organic solvent. The multi-functional antioxidant and UV light absorber includes a metal oxide particle that is to absorb UV radiation having a wavelength within a range from about 330 nm to about 405 nm and a passivating agent complexed with at least a portion of a surface of the metal oxide.
