Softening temperature (softening temperature) as rosin based resin (C) is not particularly limited, and for example preferred 80～180 ℃, preferred especially 120～170 ℃.The softening temperature of rosin based resin (C) can adopt the value of for example measuring based on JIS K 5601-2-2 (ring and ball method).
As the ratio of rosin based resin (C), be 1～50 weight part with respect to acrylic polymers (A) 100 weight parts, preferred 5～40 weight parts.Rosin based resin (C) if ratio with respect to acrylic polymers (A) 100 weight part less thaies 1 weight part, when tying up by self adhesive tape, can not fully show and prevent the anti-terminal separability peeled off from end, on the other hand, if it is more than 50 weight parts, it is really up to the mark that binder composition becomes, and do not have the bonding sense of appropriateness, and it is too small that perhaps uncoiling power becomes.
In addition, as the total amount (total amount) of petroleum resin (B) and rosin based resin (C), with respect to preferred 60 weight parts of acrylic polymers (A) 100 weight parts or 60 weight parts following (for example, 10～60 weight parts), preferred especially 10～50 weight parts.In addition, petroleum resin (B) and rosin based resin (C) if total amount surpass 60 weight parts with respect to acrylic polymers (A) 100 weight parts, it is big that the influence of the tackifying resin in binder composition becomes, cementability has the tendency that diminishes.In addition, when using the obviously low tackifying resin of intermiscibility, this intermiscibility obviously low tackifying resin comes out in the adhesive surface segregation sometimes, and the use to self adhesive tape sometimes produces obstacle.
Concrete usage quantity as petroleum resin (B) and rosin based resin (C), must be respectively the amount of above-mentioned ratio (is 1～50 weight part with respect to acrylic polymers (A) 100 weight parts), but at for example self adhesive tape is when having the self adhesive tape of body material, can carry out appropriate selection according to the composition of the thickness of the body material that uses (for example, plastic matrix material etc.) and hardness, binder composition etc.For example, self adhesive tape is the self adhesive tape that has body material, and when using plastic matrix material as body material, as body material, if body material that used thickness is thick or hard body material because anti-terminal separability has the tendency of reduction, preferably make the use level of rosin based resin (C) increase in the scope of above-mentioned ratio, thus, can obtain the anti-good self adhesive tape of terminal separability.In addition, as body material, if the thin body material of used thickness or soft and during to the favourable body material of anti-terminal separability can suppress the total amount of petroleum resin (B) and rosin based resin (C).In addition, the uncoiling power of self adhesive tape hour can increase by the use level that makes petroleum resin (B) in above-mentioned proportional range and deal with, and thus, can obtain to show the self adhesive tape of the uncoiling power of appropriateness.
In addition, in the present invention, can use softening agent.That is, softening agent can at random use.When making self adhesive tape,, thus, can bring into play the effect that makes the body material deliquescing because the softening agent in the binder layer moves in the body material with the binder layer that forms by this binder composition by in binder composition, adding softening agent.Like this, by making the body material deliquescing, the anti-terminal separability of self adhesive tape is improved, from then on viewpoint is seen, the anti-terminal separability of self adhesive tape is improved more.As softening agent, for example, [for example can use phthalic acid class softening agent, dibutyl phthalate (DBP), diheptyl phthalate (DHP), dioctyl phthalate (DOP) (DOP), diisononyl phthalate, Di Iso Decyl Phthalate (DIDP), phthalic acid two (tridecyl) ester (DTDP), phthalic acid two (three isodecyls) ester (Off Le acid ジ ト リ イ ソ デ シ Le), phthalic acid fourth lauryl, butyl benzyl phthalate], or trimellitic acid class softening agent [for example, trioctyl trimellitate (TOTM), tri trimellitate n-octyl etc.] etc., but be not limited to these, [for example can also use the fatty acid softening agent, tributyl citrate, Octyl adipate (DOA), dioctyl azelate (DOZ), dioctyl sebacate (DOS), Methylrodin etc.], phosphoric acid class softening agent [for example, phosphoric acid trimethylbenzene phenolic ester (TCP), trioctyl phosphate (TOP) etc.], epoxy plasticiser, polyester softening agent etc.Softening agent can use a kind or make up more than 2 kinds or 2 kinds and to use.The use level of softening agent is not particularly limited, if but the use level of softening agent is too much, the tackiness agent deliquescing becomes the reason of bonding bad or residual paste, therefore, with respect to preferred 30 weight parts of acrylic polymers (A) 100 weight parts or 30 weight parts following (for example, 1～30 weight part).In addition, if the use level of softening agent is few, the bating effect of the body material that is brought by softening agent reduces.
In addition, can also use linking agent.As linking agent, have no particular limits, can enumerate epoxies linking agent, isocyanates linking agent, oxazoline class linking agent etc.Linking agent can use a kind or make up more than 2 kinds or 2 kinds and to use.The use level of linking agent also has no particular limits, and can be to use the common usage quantity in binder composition.
