    Abstract: A thermosetting pressure-sensitive adhesive composition comprises a partially cross-linked saturated polyester resin, a butylated melamine-formaldehyde resin, an ethoxyline resin, a flexibilizer and an oxidation inhibitor. A solvent and/or a mineral filler may also be present. The polyester preferably comprises 65 to 85 weight per cent of the total resin mixture, and may be derived from a low molecular weight polyol, preferably a trihydric aliphatic alcohol, e.g. glycerol, butane triol, and trimethylolethane, a C7- 9 hydroxy derivative of benzoic acid, e.g. salicylic acid, a dicarboxylic acid, e.g. phthalic or iso- or terephthalic acid, and a dehydrated natural oil, e.g. dehydrated castor oil or soybean oil. The oil and part of the polyol may be pre-reacted, preferably in the presence of an initiator, e.g. Ca(OH)2, then condensed with the remaining starting materials, preferably in the presence of a condensation catalyst, e.g. isopropyl titanate. The remaining part of the resin mixture in the adhesive composition preferably comprises 3-8 weight per cent of the butylated melamine formaldehyde resin, 3-10 weight per cent of the ethoxyline resin, 3-7 weight per cent of flexibilizer, which is preferably an oil extender, e.g. castor oil or pine oil, and 1-4% of oxidation inhibitor. Suitable solvents and fillers are toluene and xylene, and iron oxide, magnesium oxide, aluminium oxide, silica, carbon black, calcium carbonate, and talc. In the examples a polyester is prepared from dehydrated castor oil, glycerol, salicylic acid and isophthalic acid in xylene i.p.o. Ca(OH)2 and isopropyl titanate. This polyester is milled with iron oxide, talc, pine oil, polymerized trimethyl dihydroquinoline and xylene, and then with an aromatic epoxy resin, castor oil and a butylated MF resin. The composition is used to dip-coat woven fibreglass tape to form a pressure-sensitive adhesive tape which may be used to insulate copper bars.ALSO:A pressure sensitive adhesive insulating tape is prepared by coating a tape with a composition comprising 65-85 wt. % of a partially cross-linked saturated oil-modified polyester resin, 3-8 wt. % of a butylated melamine formaldehyde resin, 3-8 wt. % of a flexibilizer, e.g. castor oil or pine oil, and 1-4 wt. % of an oxidation inhibitor. (see Division C3). In addition there may be present solvents, e.g. toluene and xylene, and fillers or pigments, e.g. iron oxide, aluminium oxide, magnesium oxide, silica, C black, CaCO3 and talc. In Examples a woven glass fibre tape is coated with a mixture of a glycerol/dehydrated castor oil/salicylic acid/isophthalic acid polyester milled with xylone, iron oxide, talc, pine oil, polymerized trimethyl dihydroquinoline, an epoxy resin, castor oil and a butylated MF resin.

    Abstract: A novel transparent double-sided adhesive sheet for image display device is provided, that, under the constraint of holding down the thickness of the adhesive sheet to 250 μm or less, can relieve a distortion arising within the adhesive sheet after laminating even if a member has a stepped portion of 50 μm to 100 μm in height on the laminating surface.Proposed is a transparent double-sided adhesive sheet for image display device which is used for the purpose of laminating an image display device constitutive member having on a laminating surface a stepped portion of 50 μm to 100 μm in height and a flat surface portion, and another image display device constitutive member, wherein a thickness of the maximum thickness portion of the adhesive sheet is 250 μm or less, and a gel fraction (a) at a position in contact with a stepped portion after laminating is 10% or greater and smaller than a gel fraction (b) at a position in contact with a flat surface portion.
