Title:
RESIN COMPOSITION, TONER FOR ELECTROPHOTOGRAPHY, HOT MELT COMPOSITION AND ETHYLENE/Α-OLEFIN COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2015/159557
Kind Code:
A1
Abstract:
Provided is a resin composition which contains (A) an ethylene/α-olefin copolymer that contains 91.0-99.9 parts by mole of (a) a constituent unit derived from ethylene and 0.1-9.0 parts by mole of (b) a constituent unit derived from an α-olefin having 3-8 carbon atoms (so that (a) + (b) is 100 parts by mole), while satisfying the requirements (i)-(iv) described below and (B) a thermoplastic resin and/or a thermosetting resin, and wherein the mass ratio of (A) to (B) is from 0.1/99.9 to 50/50. This resin composition is useful for providing a toner which can be fixed by means of a relatively-low-temperature heating body and has good offset resistance, and which is suppressed in increase of particle diameters even if the toner is stored for a long period of time. (i) The weight average molecular weight (Mw) is within the range from 400 to 1,500. (ii) The molecular weight distribution (Mw/Mn) is within the range from 1.2 to 2.5. (iii) The penetration as measured at 25°C is 13 dmm or less. (iv) The melting point (Tm) is within the range from 50°C to 110°C.
