Document Type and Number:
WIPO Patent Application WO/2022/163394
Kind Code:
A1
Abstract:
Provided is a hydrocarbon resin including aliphatic-monomer units or including aliphatic-monomer units and aromatic-monomer units, characterized by having a number-average molecular weight (Mn) in the range of 400-3000, a weight-average molecular weight (Mw) in the range of 700-6000, a Z-average molecular weight (Mz) in the range of 1500-20000, a ratio (Mw/Mn) of the weight-average molecular weight to the number-average molecular weight in the range of 1.0-4.0, a ratio (Mz/Mw) of the Z-average molecular weight to the weight-average molecular weight in the range of 1.0-4.0, and a ratio of the peak-top molecular weight to the weight-average molecular weight (Mw), (peak-top molecular weight)/Mw, in the range of 0.7-1.2 and by having a softening temperature in the range of 80-150°C.
