Description of the Invention: [Technical Field of the Invention] The present invention relates to a method for producing an adhesive composition, an adhesive composition, a material (a material of a parent adhesive composition), and adhesion In particular, the present invention relates to a dry composition suitable for use as an optical member such as a polarizing plate, a method for producing an adhesive composition, a dot, and a tablet. [Prior Art] As in the case of a liquid crystal panel, a polarizing plate or a retardation plate is bonded to a glass substrate or the like, and an adhesive layer formed of an adhesive composition is often used. However, the optical member such as a polarizing plate or a phase difference plate is likely to shrink due to heat or the like, and therefore shrinks due to the heat history. As a result, it is pointed out that the adhesive layer laminated on the optical member cannot track its shrinkage. The interface is peeled off (so-called floating, peeling), or a problem occurs in light leakage (so-called whitening) caused by the deviation of the optical axis of the optical member due to the stress caused by shrinkage of the optical member. As a method for preventing this, a method of suppressing shrinkage of an optical member by bonding an adhesive layer having a high adhesive force and good formability to an optical member such as a polarizing plate or the like is 2) A method of using an adhesive layer having a small stress when the optical member is shrunk. As a method of (丨), as shown in Patent Document 1, an adhesive layer having a high storage modulus is used. On the other hand, as the method (2), an adhesive layer which is soft in response to deformation and which has a good stress relaxation property is effectively used. However, in the state in which an attempt is made to form such an adhesive layer having good stress relaxation, 4 201122071 must extremely reduce the density of the parent in the layer a. In such a case, there is a problem that the strength of the adhesive layer itself is lowered and the durability is deteriorated. Then, in Patent Document 2 to /Aminoethyl phthalate elastomer, the crosslinker composition of the binder layer is extremely reduced, and the light leakage resistance and durability are obtained in the adhesive layer. 'Using a plasticizer, a fluid sarcophagus, and a propylene-based adhesive to replace the density-moderately softened and imparted stress relaxation, in an attempt to use this [Prior Art Document] • [Patent Document] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei.

The plasticizer or the fluid paraffin flows out, and various problems such as contamination of the liquid crystal cell occur. In addition, when the adhesive composition of the elastomer of the urethane is added, it is limited by the compatibility with other components, and the amount of the urethane elastomer is limited. Therefore, the stress relaxation property is improved. The improvement is insufficient, and the problem of white turbidity or the like occurs due to the compatibility of the propylene-based adhesive and the amino-based phthalic acid ethyl ester elastomer. 5 201122071 As described above, in the prior art, it is not easy to fundamentally improve the light leakage resistance and durability of the adhesive layer formed of the adhesive composition for an optical member.

The money and durability are both good 201122071 [ EMBODIMENT OF THE INVENTION The following description of the embodiment of the present invention will be described. (Adhesive composition) The adhesive composition of the present embodiment contains the first one having a weight average molecular weight of 70,000 to 250,000. The acrylate copolymer, the second (fluorenyl) acrylate copolymer (B) having a weight average molecular weight of 8,000 to 250,000, and the crosslinking agent (C) preferably further contain a decane coupling agent (D). Further, in the present specification, the term "fluorenyl" acrylate means both acrylate and methacrylate. Other similar terms are also the same. The second (fluorenyl) acrylate copolymer (b) is The monomer having a functional group (bl) having high reactivity with the crosslinking agent (C) is used as a structural component. The composition ratio of the copolymer (B) of the monomer is more than 1% by mass. The (meth) acrylate copolymer (A) of the first embodiment does not contain a monomer having a functional group reactive with the crosslinking agent (C), and is a structural component 'or hydrazine and a crosslinking agent (C). The aforementioned functional group having lower reactivity than the second (fluorenyl) acrylate copolymer (B) The monomer of the functional group (ai) of bl) is used as a structural component. The above (meth) acrylate copolymer (A) or (B) is preferably an alkyl group having an alkyl group having a carbon number of 1 to 2 〇. a copolymer of a (mercapto) acrylate and a reactive functional group-containing monomer (containing a reactive functional group monomer) and other monomers used as required. In addition, the first (meth)acrylic acid vinegar The copolymer (A) is preferably a structural component which does not contain the reactive functional group-containing monomer. The alkyl group having an alkyl group as an ester moiety is 1 to 2 fluorene (mercapto) acrylic acid 10 201122071 series, for example (曱基)acrylic brewing, (mercapto) acrylic vinegar, X bauxite, acrylic acid, (meth) butyl acetonate, (meth) propylene pentane, (meth) acrylate Hexyl ester '(fluorenyl) hexyl hexyl acrylate, 2-ethylhexyl (meth) acrylate, isobutyl vinegar (meth) acrylate, (decyl) acrylic acid hexamethacrylate Lipid and so on. Anthracene vinegar, (decyl) decyl acrylate, (mercapto) '(meth) hexadecane hydride, (mercapto) propyl. These may be used alone or in combination of two or more. On the other hand, as the reactive functional group-containing single system, a monomer having a hydroxyl group in the molecule (hydroxy group-containing monomer), a monomer having a carboxyl group in the molecule (including a tetamine monomer), and a molecule are preferably used. A monomer having an amine group (an amine group-containing monomer) or the like. Examples of the hydroxyl group-containing monomer include 2-hydroxyethyl 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylic acid, and 2-hydroxybutyl (meth)acrylate. A (meth)acrylic acid hydroxyalkyl ester such as (meth) propylene 13 hydroxybutyl or (meth)acrylic acid 4-hydroxybutyl group. These systems may be used alone or in combination of two or more. Examples of the three repellent monomer series include ethylenically unsaturated carboxylic acids such as acrylic acid, methacrylic acid 'butene & maleic acid, itaconic acid, citraconic acid, and vinyl acetate. These systems may be used singly or in combination of two or more. As a series of amine-containing monomers, for example, aminoethyl (meth)acrylate, N,N-dimethylaminoethyl (meth)acrylate, (meth)acrylic acid 11 201122071 methyl)acrylic acid t-butyl Further, it is also possible to combine two or more kinds of N,N--fluorenylaminopropyl groups, and the like. These lines can be used separately. In addition, as the other monomer series, an aromatic ring having an aliphatic ring such as (meth)acrylic acid vinegar or (meth)acrylic acid ester such as (meth)acrylic acid cyclohexene (Amidyl) (tetra) non-crosslinkable acrylamide, styrene, etc., such as an acid ester, acrylamide, decyl acrylamide. These systems may be used alone or in combination of two or more. Further, the reactivity of the reactive functional group (al) monomer used in the first (meth) acrylate copolymer (A) and the (meth) acrylate copolymer (B) used in the second The choice of functional group (bl) monomer is determined by the reactivity of the crosslinker (C) used. The details are stated in the back. Here, the second (fluorenyl) acrylate copolymer (b) contains the reactive functional group (bl) monomer in an amount exceeding 丄 mass%, and the upper limit is usually 50% by mass. It is preferable to contain 3 to 40% by mass of the above-mentioned reactive functional group (bl) monomer, and particularly preferably 5 to 25% by mass. By containing the reactive functional group (bl) monomer in the above range ', and preferably the second (fluorenyl) acrylate copolymer (B), the degree of crosslinking is the same as that of the first The combination of the acrylate copolymer (A) and the stress relaxation property of the obtained primer are good. Further, the content of the reactive functional group (bl) monomer is 1% by mass or less. The second (indenyl) acrylate copolymer (B) is insufficiently linked. This reduces the longevity. On the other hand, when the content of the reactive functional group (bl) monomer exceeds 12 201122071 t 50 mass %, the parental relationship of the second (meth) acrylate copolymer (b) becomes excessive, I am afraid that this will reduce the suitability of the attachment to the attached body. Further, the upper limit of the content of the monomer having a reactive functional group (bl) is 40% by mass, so that the durability of the adhesive sheet is further improved. In the present embodiment, the second (meth)acrylate-based copolymer (B) may be used alone or in combination of two or more. The weight average molecular weight of the second (fluorenyl) acrylate copolymer (B) is 8,000 to 250,000, preferably 20,000 to 150,000. That is, the second (fluorenyl) acrylate copolymer (Β) is a low molecular weight polymer forming tool. Further, the weight average molecular weight of the present specification is determined by gel permeation chromatography (GPC). The value of stupid ethylene conversion. Since the weight average molecular weight of the second (fluorenyl) acrylate copolymer is within the above range, the adhesive composition of the present embodiment forms a unique three-dimensional mesh structure, which contributes to good stress relaxation. That is to say, in the second (fluorenyl) weight average molecular weight is less than 8 〇〇〇, a good three-dimensional network structure is not obtained, and the second (fluorenyl) acrylic acid vinegar copolymer (Β) When the weight average molecular weight exceeds 250,000, the compatibility is lowered, and the copolymer (A) and the copolymer (β) are not easily entangled, and it is not easy to form a mesh structure peculiar to the purpose, which is deteriorated in durability and Reworkability. The first (meth) acrylate copolymer ") is a structural component which does not contain a functional group having reactivity with a parent conjugate (C), or 13 201122071 which contains a crosslinking agent and a crosslinking agent (c) a steroid having a lower reactivity than the functional group (ai) of the aforementioned functional group (Μ) of the (meth) acrylate copolymer (B), as a structural component, and then preferably It is a structural component which does not contain the functional group which has the high reactivity with the crosslinking agent (C). The (meth) acrylate copolymer (A) of the first embodiment may not contain a monomer having a functional group reactive with the crosslinking agent (C), but contains a reactivity lower than that of the second (A) When the monomer of the reactive functional group (al) of the reactive functional group (b1) of the acrylate copolymer (b) is used, the second (meth) acrylate copolymer (B) and the crosslinking agent are promoted ( The reaction of c), or in the state of using the decane coupling agent (D), the reactive functional group (al) of the first (fluorenyl) acrylate copolymer (A) is reacted with the decane coupling agent (D). The alkoxymethyl sulfonyl group or the like can adjust the degree of aggregation of the bis(indenyl) acrylate copolymer (A), and the desired bonding property can be obtained. In the state in which the first (fluorenyl) acrylate copolymer (A) contains the reactive functional group (al) monomer, the content thereof is usually 2% by mass or less, preferably 15% by mass or less. In particular, it is preferable that the first (meth) acrylate copolymer (A) is excessively aggregated when the content of the reactive functional group (al) monomer exceeds 20% by mass. Will not be able to get the required stress mitigation. Further, the content of the reactive functional group (al) monomer is preferably 15% by mass or less from the viewpoint of imparting reworkability. The first (meth) acrylate copolymer (A) is preferably one which does not contain a acrylate copolymer having a reactivity equivalent to that of the crosslinking agent (c) in the molecule or more than that of the second (A14, 2011,201,071,071) acrylate copolymer. (B) a monomer having a functional group of a reactive functional group (bl), but it is assumed that, in the state of being contained, a monomer having a functional group in the molecule is preferably a copolymer (A) In the case of 1% by mass or less, particularly preferably 0.5% by mass or less. When the content of the monomer exceeds 1% by mass, the reaction of the second (fluorenyl) acrylate copolymer (B) and the crosslinking agent (C) which should be preferentially reacted may be hindered. In the present embodiment, the first (nonyl) acrylate copolymer (A) may be used singly or in combination of two or more. The weight average molecular weight of the first (meth) acrylate copolymer (A) is from 700,000 to 2.5 million', preferably from 1,000,000 to 2,000,000. That is, the first (fluorenyl) acrylate copolymer (Α) is a high molecular weight polymer component. The weight average molecular weight of the first (fluorenyl)propionic acid g copolymer (Α) is in the above range, and the second (fluorenyl) acrylate acid copolymer (B) is formed. The ternary mesh structure is excellent in winding the first (meth) acrylate copolymer (A), contributing to good stress relaxation, and adhesion to the adherend or in high heat and humidity conditions. The lower joint durability is sufficient to prevent floating, peeling, and the like. Here, when the weight average molecular weight of the first (meth) acrylate copolymer (A) is less than 700,000, the cohesive force of the component (A) is lowered, and the durability and reworkability may be deteriorated. Further, in the case where the weight average molecular weight of the thiol 7 acryl vinegar copolymer (A) exceeds 250,000, the obtained drilling agent is excessively hard, and the required stress relaxation may not be obtained 15 201122071. 2 ^ ( fluorenyl) internal dilute acid copolymer (B) relative to 1 〇〇 part by mass of the first r 篁, 旦) acrylate copolymer (A) ratio of 5 to 50 i injured most It is 1 〇 to 3 〇 mass parts.

As a series of aluminum chelate compounds, for example, diisopropoxy oil, sulphuric acid, acenaphthyl acetate, monoisopropoxy Acetate, monoisopropoxy aluminum monooleate monoethyl acetoacetate, diisopropoxy aluminum monolaurylacetate acetate, diisopropoxy aluminum monostearate Acetate, diisopropoxy aluminum monoisostearate, acetonitrile acetate, etc. These may be used alone or in combination of two or more. The content of the crosslinking agent (C) Preferably, the crosslinking agent (◦) is crosslinked 17 201122071 in an amount of 0.1 to 5 equivalents, particularly preferably 〇. 2, the amount of the crosslinking group is less than 〇. 1 equivalent by time adhesion Poor reworkability. The reactive functional group of the group (for example, isocyanate group) relative to the copolymer (B) exceeds the amount of the crosslinkable group described above. The amount of (曱) acrylate bl) (for example, a hydroxyl group) is equivalent to an amount. In the case where it is feared that the cross-linking amount may not be sufficiently performed, the attachment may be improved. In addition, in the present embodiment, in addition to the aforementioned cross-linking In addition to the agent (C), it is also possible to use a reactive functional group (al) of the copolymer (A) having a reactivity higher than that of the copolymer (B) reactive functional group (bl) without impairing the effects of the present invention. Other cross-linking agent having reactivity (indicating that a cross-linking agent of a type other than the cross-linking agent having the most added amount in the state in which two or more kinds of cross-linking agents are used in combination is used) When the reactive functional group (al) of the substance (a) is a carboxyl group and the reactive functional group (b1) of the copolymer (B) is a hydroxyl group and the crosslinking agent (c) is an isocyanate crosslinking agent, the other is A small amount of an epoxy crosslinking agent can be added to the parent crosslinking agent. The addition of such other crosslinking agent is in the three-dimensional network structure 4 composed of the copolymer (B), and the copolymer (A) is not sufficiently wound to be effective in a state in which the cohesive force is insufficient. In the state in which the other crosslinking agent is added, the amount thereof is preferably 〇1 to 1 part by mass based on 1 part by mass of the total of the copolymers (A) and (B). Here, the combination of the reactive functional group-containing monomer as the crosslinking agent (C) and the (meth) acrylate copolymers (A) and (B) is an isocyanate-based crosslinking agent (C). In the state of the crosslinking agent, it is preferred to select a carboxyl group-containing monomer as the reactive functional group (ai) monomer of the copolymer (A), and select a hydroxyl group monomer or an amine group-containing monomer containing 18 201122071 as The reactive functional group (bl) monomer of the copolymer (B). On the other hand, in the state where the crosslinking agent (C) is an epoxy crosslinking agent, azacyclopropene crosslinking agent or a metal chelate crosslinking agent, it is preferred to select a hydroxyl group-containing monomer. As the reactive functional group (al) monomer of the copolymer (A), a carboxyl group-containing monomer is selected as the reactive functional group (bl) monomer of the copolymer (β). Because of the softness of the bond formed between the crosslinking agent (C) and the copolymer (β) and the stability of the crosslinking reaction, even the reactive group of the copolymer (Β) is moderately reacted with the decane coupling agent (D). Further, it contributes to an increase in the cohesive force of the copolymer (Β), and therefore it is particularly preferable that the crosslinking agent (c) becomes a reactive functional group (al) monomer of the isocyanate coupling agent 'A (A). The reactive functional group (bl) monomer which becomes a monomer-containing monomer 'β (β) becomes a hydroxyl group-containing monomer. The adhesive composition of the present embodiment preferably further contains a decane coupling agent (D). In the case where the decane coupling agent (D) is contained, the alkoxymethyl sulfonyl group of the coupling agent (4) and the like are in the state in which the (meth) acrylic acid (the) copolymer (1) has a (d) group. Since the thiol group of the (meth) acrylate copolymer (1) reacts, the degree of aggregation of the (meth) succinic acid ruthenium copolymer (A) can be adjusted to obtain the desired bondability. Further, when the setting agent (D) is contained, for example, in a state in which the polarizing plate is bonded to the liquid crystal cell or the like, the adhesion between the drying agent and the liquid crystal glass cell is further improved. The organic coupling agent (1) is an organic stone compound having at least i calcining oxygen 19 201122071 ketone group in the molecule, and has good compatibility with a dry agent component, and has light permeability, for example, In essence, it is suitable for transparency. The amount of the sulphur coupling agent (D) to be added is preferably 〇〇5 to 〇·5 parts by mass relative to 1 part by mass of the first (meth)acrylic acid vinegar copolymer (1).

In the above-mentioned drilling composition, various additives generally used for the propylene-based drying agent, such as a spotting agent, an oxidation inhibitor, an ultraviolet absorber, a light stabilizer, a softener, a filler, and a charge, may be added as required. Preventing agent, refractive index adjusting agent, and the like. [Manufacturing Method of Charming Composition] The above-described adhesive composition can be produced, for example, as follows. Namely, it is preferable to prepare (meth)acrylic acid copolymers (1) and (B) in each of the polymerization solvents described later by the usual radical polymerization method. Next, the solution of the two copolymers obtained by mixing is added to a diluted solvent so that the solid concentration becomes 1 () to 4 〇 20 201122071 % by weight. Finally, by adding the crosslinking agent (c) and the ceramsite coupling agent (D) in this order, the mixing is sufficiently carried out to obtain an adhesive composition diluted with a solvent. Further, the above-mentioned adhesive composition is preferably produced by a series of polymerizations shown below. Specifically, (1) the monomer constituting the first (fluorenyl) acrylate copolymer (A) is subjected to radical polymerization at a conversion ratio of 50 to 90% to produce the first (meth)acrylic acid. After the ester copolymer (A); (2) in the presence of the first (meth) acrylate copolymer (A), for the (meth) acrylic acid a | copolymer remaining in the first (A) The monomer at the time of polymerization and the monomer having a high reactivity (bi) with the crosslinking agent (C) and other monomers used as required, preferably at a conversion rate of 70~ The base copolymerization is carried out to produce a second (meth)acrylic acid vinegar:polymer (8), followed by (3) a crosslinking agent (c) and/or a crosslinking agent (D) (the component (D) is required). The 帛(曱-based) acrylate copolymer (A) constituting the process (1) I has a carbon number of i 2n as the former, and preferably an alkyl group containing at least a vinegar moiety (2 2° (A) Base) two dilute acid vinegar.

Series polymerization, moderately adjusting the ratio of the monomer (meth) acrylate copolymer (A) and the (meth) acrylate copolymer (B) and the functional group Content becomes the aforementioned Further, the polymerization conditions are moderately adjusted so that the weight average molecular weight of the (meth) acrylate copolymer (A) and the (meth) acrylate copolymer (B) of the second oxime becomes the aforementioned range. [Adhesive] The adhesive of the present embodiment is composed of crosslinked Moss, 'I. # quoting the dry composition, and the cross-linking of the dry composition', by heat treatment Further, the heat treatment system may be subjected to a drying treatment in the case where a solvent or the like of the volatile adhesive composition is diluted.

The dot layer formed by arranging the drying agent has very good stress relaxation property. Therefore, even in the state where the size of the adherend changes greatly, it can be absorbed by the layer of the coating agent. The relaxation can produce a stress of 23 201122071 due to the dimensional change thereof, so that it is not easily peeled off by the adherend after a long period of time, and at the same time, 'when used in the aforementioned optical member', the light leakage can be effectively prevented. That is to say, the binder of the present embodiment achieves both light leakage resistance and durability.
