    Abstract: The present disclosure relates to a color-changing composition comprising:
    a) a dye selected from the group consisting of metal complexes, wherein the metal complexes comprise:
    i. a central ion of a metal selected from the group consisting of iron, vanadium, chromium, manganese, cobalt, nickel and copper; and
    ii. chelate ligands having heteroaromatic structures;

    b) an adhesive composition;
    c) optionally, a curable polymer resin selected from the group consisting of epoxy resins, polyester resins, polyurethane resins, vinyl resins, and any combinations or mixtures thereof;
    wherein the color-changing composition has an initial color and is capable of changing color to a final color upon contacting a curable composition comprising one or more curing agents and a curable polymer resin; wherein the one or more curing agents are suitable to cure the curable polymer resin; and wherein the initial color is different from the final color.

    Abstract: A main object of the present invention is to provide a modified hydrocarbon resin that provides a hot melt adhesive composition with low odor, excellent heat stability, and high adhesive properties. The present invention achieves the object by providing a modified hydrocarbon resin obtained by hydrogenating a hydrocarbon resin comprising: a 1,3-pentadiene monomeric unit of 20 mass% to 70 mass%, a C 4-6 alicyclic monoolefin monomeric unit of 10 mass% to 35 mass%, a C 4-8 acyclic monoolefin monomeric unit of 5 mass% to 30 mass%, an alicyclic diolefin monomeric unit of 0 mass% to 1 mass%, and an aromatic monoolefin monomeric unit of 0 mass% to 40 mass%, the modified hydrocarbon resin being characterized in that: a degree of hydrogenation of the olefins is within a range of 30% to 80%; a degree of hydrogenation of the aromatic rings, if an aromatic monomeric unit is included, is within a range of 5% to 20%; a weight average molecular weight (Mw) is within a range of 1,000 to 4,000; a Z-average molecular weight (Mz) is within a range of 2,500 to 10,000; a ratio (Mz/Mw) of the Z-average molecular weight to the weight-average molecular weight is within a range of 1.5 to 2.5; a Gardner color scale of a toluene solution of 50 mass% is 2 or lower; and a difference between pre-hydrogenation and post-hydrogenation mixed aniline point (MMAP) is 5°C or less.

    Abstract: Provided is a method for producing a multilayer member exhibiting excellent adhesion. A method for producing a multilayer member having a first member containing a crystallizable thermoplastic resin, an adhesion layer, and a second member in this order includes a surface treatment step of performing a dry treatment on a surface of the first member containing a crystallizable thermoplastic resin so as to satisfy the following conditions A and B, an adhesive application step of applying an adhesive to the surface of the first member subjected to the dry treatment without a primer composition, to form an adhesive layer on the surface, and an adhering step of adhering the second member to the adhesive layer.
    (A) The ultimate temperature of the first member is lower than the peak temperature of endothermic peak obtained by differential scanning calorimetry of the crystallizable thermoplastic resin.
    (B) The high temperature holding time of the first member is less than 3.0 seconds. Herein, the high temperature holding time of the first member is a time when the first member is continuously held at a temperature not lower than a temperature at the starting point of the endothermic peak obtained by differential scanning calorimetry of the crystallizable thermoplastic resin.
