A film for glass lamination comprising:
- a pigment portion occupying some or a whole of the film,
- wherein the pigment portion comprises an extruded pigment layer comprising a mixture of a polyvinyl acetal resin, a pigment, a plasticizer, and a trioxane-based compound,
- wherein the trioxane-based compound has a structure of Formula 1 below;
- in formula 1, R1, R2, and R3 are each independently hydrogen or alkyl group having 1 to 5 carbon atoms, expect that at least one of R1, R2, and R3 is an alkyl group having 1 to 5 carbon atoms;
- wherein the trioxane-based compounds is comprised in an amount of 0.001 to 3 wt % with respect to a total weight of the extruded pigment layer.
