Abstract:
1. A polyolefin wax (B) for a coating material comprising an ethylene (co)polymer (A) having a number average molecular weight (Mn) within the range of from 400 to 5000 as measured by gel permeation chromatography (GPC), said polyolefin wax having a mean volume particle diameter in the range of from 0.3 μm to 20 μm wherein the relation between a particle diameter a (μm), in which the weight ratio of the larger particle diameter side in weight particle size distribution is 10%, and a particle diameter b (μm), in which the weight ratio of the smaller particle diameter side in weight particle size distribution is 10%, satisfies the following equation (I): and the relation between the crystallization temperature Tc (° C.) of the ethylene (co)polymer (A), measured at a cooling rate of 2° C./min as measured by differential scanning calorimetry (DSC) and the density D (kg/m 3 ) of the ethylene (co)polymer (A) as measured by the density gradient tube method satisfies the following equation (II):
