Dependent claims

A multilayered polymeric film comprising:

an outer polymeric layer comprising a foaming agent and an inner polymeric layer comprising a polymeric resin and a special effect agent, wherein
the foaming agent in the outer polymeric layer produces a cellular structure at a side of the outer polymeric layer that is opposite the inner polymeric layer,
the special effect agent in the inner polymeric layer reflects through the cellular structure in the outer polymeric layer to create a multi-dimensional visual effect, and
the foaming agent comprises azo compounds, N′-nitroso compounds, sulfonyl hydrazide compounds, inorganic carbonates, polycarboxylic acids, or mixtures thereof.
