摘要：
Processes for obtaining new composite preforms (26) suitable for blow-molding made of at least two different materials (4, 22), preforms obtained thereby, and articles obtained by blow-molding of these preforms. The processes employ the injection-molding of two (or more) plastic materials to form preforms that can be blow-molded into articles. In a preferred embodiment, the two materials have different colors and the resulting articles show a multi-colored effect. The two materials are not laminated over each other.
