The disclosure provides a laminated polyolefin microporous membrane having propylene-α-olefin copolymer and methods of producing the same. The laminated polyolefin microporous membrane has a two-type three layer structure in which first polyolefin microporous layers are surface layers and a second polyolefin microporous layer is an intermediate layer which is different from the first polyolefin microporous layer.

Three dimensionally printed aesthetic particles that are water dispersible are provided. Each particle has a first side and a second side, while the first side has a length from 0.2 mm to 20 mm. Further, such particles have at least two voids, while the at least two voids are each a through hole extending between the first side and the second side.
