Description
Technical Field
The present invention relates to a surface protective film. Further, it relates to providing an optical laminate comprising such a surface protective film.
Background
A surface protective film is provided on the surface of an optical device such as a display or an imaging device, an electronic device, a film as a component of such a device, a glass material, or the like for the purpose of surface protection, impact resistance, or the like. As the surface protective film, there are typically: temporarily adhering the film (film used as a processing material) to the device before use, such as temporarily adhering the film to the device before use; a film (film for the purpose of permanent adhesion) that is used in a state of being adhered to the surface of the device as it is also used in the device (for example, see patent document 1).
The surface protective film used as a processing material and the surface protective film for permanent adhesion each have an adhesive layer on a main surface of a film base material, and are bonded to a surface of an adherend to be protected via the adhesive layer (for example, see patent literature 2).
Optical members including polarizing plates, such as liquid crystal display devices, are generally inspected as examples for the purpose of evaluating color/brightness unevenness. However, in the case of performing inspection of color/brightness unevenness of an optical laminate in which a surface protective film is bonded to an optical member including a polarizing plate through a surface protective film, there is a case where proper inspection cannot be performed due to anisotropy or the like of the surface protective film.

< one preferred embodiment of the substrate A >
One preferred embodiment a of the substrate is a stretched thermoplastic resin substrate. Hereinafter, the thermoplastic resin substrate to be stretched may be simply referred to as "thermoplastic resin substrate", and the stretched thermoplastic resin substrate may be referred to as "stretched thermoplastic resin substrate".
The thickness of the stretched thermoplastic resin substrate according to embodiment a may be any suitable thickness within a range that does not impair the effects of the present invention. In order to further exert the effects of the present invention, the thickness of the stretched thermoplastic resin substrate is preferably 1 μm to 100. Mu.m, more preferably 2 μm to 80. Mu.m, still more preferably 3 μm to 70. Mu.m, particularly preferably 5 μm to 60. Mu.m.
The front phase difference R0 of the stretched thermoplastic resin substrate is preferably not more than 2500nm, more preferably not more than 2100nm, further preferably not more than 1700nm, further preferably not more than 1300nm, further preferably not more than 1000nm, particularly preferably not more than 800nm, most preferably not more than 700nm, of R0. If the frontal phase difference R0 of the stretched thermoplastic resin substrate is within the above range, the effects of the present invention can be further exerted.
The lower limit value of the frontal phase difference R0 of the stretched thermoplastic resin substrate is preferably as small as possible, but is practically preferably 100nm or more depending on factors such as material selection.
The thermoplastic resin base material preferably has a water absorption rate in a predetermined range in order to further exhibit the effects of the present invention. The water absorption rate of the thermoplastic resin base material is preferably 0.2% or more, more preferably 0.3% or more. The thermoplastic resin base material having such water absorption rate absorbs water during stretching in water, which will be described later, and the water acts as a plasticizer to plasticize. As a result, the tensile stress can be greatly reduced, and the thermoplastic resin substrate can be stretched to a high magnification, and the stretchability of the thermoplastic resin substrate is more excellent than in the case of air stretching, which will be described later. If such a thermoplastic resin substrate is stretched, a substrate having excellent optical characteristics can be formed, and therefore the effects of the present invention can be further exerted. On the other hand, the water absorption rate of the thermoplastic resin base material is preferably 3.0% or less, more preferably 1.0% or less. The thermoplastic resin base material having such water absorption is excellent in dimensional stability, and therefore, the thermoplastic resin base material can be prevented from being stretched to have a poor appearance, and the base material can be prevented from being broken in an underwater stretching step described later. The water absorption was obtained according to JIS K7209.
The thermoplastic resin base material preferably has a glass transition temperature (Tg) in a predetermined range in order to further exhibit the effects of the present invention. The glass transition temperature (Tg) of the thermoplastic resin substrate is preferably 170℃or lower. By using such a thermoplastic resin substrate, excellent stretchability can be exhibited. Further, in view of plasticization of the water-based thermoplastic resin base material and good underwater stretching, the glass transition temperature (Tg) of the thermoplastic resin base material is preferably 120 ℃ or lower. On the other hand, the glass transition temperature (Tg) of the thermoplastic resin substrate is preferably 60℃or higher. By using such a thermoplastic resin base material, it is possible to prevent the thermoplastic resin base material from being deformed (for example, having irregularities, looseness, wrinkles, and the like). The glass transition temperature (Tg) is a value obtained according to JIS K7121.
As a material of the thermoplastic resin base material, in order to further exert the effects of the present invention, a material having water absorption and glass transition temperature of the thermoplastic resin base material in the above-described range is preferable. The water absorption can be adjusted, for example, by introducing modifying groups into the material. The glass transition temperature can be adjusted, for example, by introducing modifying groups into the material, by using a crystalline material, and heating.
As a material of the thermoplastic resin base material, in order to further exhibit the effect of the present invention, a polyethylene terephthalate (PET) resin is preferable, an amorphous (uncrystallized) polyethylene terephthalate (PET) resin is more preferable, and an amorphous (hardly crystallized) polyethylene terephthalate (PET) resin is more preferable. Specific examples of the amorphous polyethylene terephthalate (PET) resin include: further comprising a copolymer of isophthalic acid as a dicarboxylic acid and further comprising cyclohexanedimethanol as a diol.
The thickness (thickness before stretching) of the thermoplastic resin base material is preferably 10 μm to 500 μm, more preferably 20 μm to 400 μm, still more preferably 30 μm to 300 μm, particularly preferably 50 μm to 200 μm, in order to further exert the effect of the present invention.
As for stretching of the thermoplastic resin substrate, in-water stretching (wet stretching) using a water bath as a stretching bath is typical. By using the stretching in water, if the thermoplastic resin base material has the water absorption rate as described above, the water acts as a plasticizer and plasticizes. As a result, the tensile stress can be greatly reduced, and the thermoplastic resin substrate can be stretched to a high magnification, and the stretchability of the thermoplastic resin substrate is more excellent than in the case of air stretching, which will be described later. Therefore, a substrate having excellent optical characteristics can be obtained, and thus the effects of the present invention can be further exerted. Further, by employing in-water stretching, stretching to a high magnification can be performed at a temperature lower than the glass transition temperature of the thermoplastic resin substrate.
The stretching direction of the thermoplastic resin base material is preferably the transverse direction (short side direction) of the long thermoplastic resin base material.
As the stretching method of stretching in water, any suitable method may be employed within a range that does not impair the effect of the present invention. Examples of such stretching methods include: fixed end stretching, free end stretching (for example, a method in which a laminate is uniaxially stretched between rolls having different peripheral speeds). The stretching may be performed in one stage or may be performed in multiple stages. In the case of performing in multiple stages, the stretching magnification (maximum stretching magnification) is a product of stretching magnifications of the respective stages.
As for the stretching temperature (liquid temperature of the stretching bath) of the stretching in water, any suitable temperature may be employed within a range that does not impair the effect of the present invention. In order to further exert the effects of the present invention, it is preferably 30℃or higher, more preferably 40℃to 90℃and still more preferably 45℃to 85℃and particularly preferably 50℃to 80 ℃. If the temperature of the stretching bath is too low, there is a concern that the stretching may not be performed satisfactorily even if plasticization of the water-based thermoplastic resin substrate is considered.
As for the stretching time of stretching in water, any suitable time may be used within a range that does not impair the effect of the present invention. In order to further exert the effects of the present invention, it is preferably 15 seconds to 5 minutes.
The maximum stretching ratio of the stretching in water is preferably 5.0 times or more with respect to the original length of the thermoplastic resin substrate. In the present specification, the "maximum stretch ratio" means a stretch ratio immediately before breaking of the base material, and a stretch ratio at which breaking of the base material is separately confirmed means a value lower than this by 0.2. In addition, regarding the maximum draw ratio, the draw ratio in water is higher than that in the case of drawing by dry drawing alone.
As the stretching of the thermoplastic resin substrate, the above-mentioned in-water stretching and air stretching (dry stretching) may be combined. The air stretching may be performed by any suitable stretching method within a range that does not impair the effects of the present invention. By combining in-water stretching and air stretching, stretching can be performed while suppressing orientation of the thermoplastic resin substrate. As the orientation of the thermoplastic resin substrate increases, the tensile strength increases, and it is difficult to stably stretch the thermoplastic resin substrate or the thermoplastic resin substrate breaks. Accordingly, by stretching while suppressing the orientation of the thermoplastic resin base material, it is possible to stretch to a higher magnification. As a result, a substrate having more excellent optical characteristics can be obtained, and therefore the effects of the present invention can be further exerted.
The stretching method of the air stretching may be fixed-end stretching or free-end stretching (for example, a method of stretching a laminate unidirectionally by passing the laminate between rolls having different circumferential speeds) as in the case of the above-described underwater stretching. The stretching may be performed in one stage or may be performed in multiple stages. In the case of performing in multiple stages, the stretching magnification is the product of the stretching magnifications of the respective stages. The stretching direction is preferably substantially the same as the stretching direction of the above-described in-water stretching.
As for the stretching temperature of the air stretching, any suitable temperature may be employed within a range that does not impair the effect of the present invention. In order to further exert the effect of the present invention, the stretching temperature in the air stretching is preferably 95 to 150 ℃.
As for the stretching time of the air stretching, any suitable time may be employed within a range that does not impair the effect of the present invention. In order to further exert the effects of the present invention, the stretching time in air stretching is preferably 15 seconds to 5 minutes.
The stretching ratio of the air stretching may be any suitable ratio within a range that does not impair the effect of the present invention. In order to further exert the effects of the present invention, the stretching ratio in air stretching is preferably 3.5 times or less.
The maximum stretching ratio when combining air stretching and underwater stretching is preferably 5.0 times or more, more preferably 5.5 times or more, and even more preferably 6.0 times or more, relative to the original length of the thermoplastic resin substrate.

The laminate was uniaxially stretched to 2 times in the longitudinal direction (longitudinal direction) between rolls having different peripheral speeds in an oven at 120 ℃, then immersed in an insoluble bath at a liquid temperature of 30 ℃ (an aqueous boric acid solution obtained by compounding 4 parts by weight of boric acid with 100 parts by weight of water), then immersed in a dyeing bath at a liquid temperature of 30 ℃ (an aqueous iodine solution obtained by compounding 0.2 parts by weight of iodine with 100 parts by weight of potassium iodide) for 60 seconds, then immersed in a crosslinking bath at a liquid temperature of 30 ℃ (an aqueous boric acid solution obtained by compounding 3 parts by weight of potassium iodide with 3 parts by weight of boric acid with 100 parts by weight of water), then immersed in an aqueous boric acid solution at a liquid temperature of 60 ℃ (an aqueous boric acid solution obtained by compounding 4 parts by weight of potassium iodide with 5 parts by weight of water), and simultaneously uniaxially stretched in the longitudinal direction (longitudinal direction) between rolls having different peripheral speeds. The immersion time in the aqueous boric acid solution was 120 seconds, and stretching was performed until the laminate was immediately before breaking.
Then, the laminate was immersed in a washing bath (an aqueous solution obtained by mixing 3 parts by weight of potassium iodide with 100 parts by weight of water), and then dried with warm air at 60 ℃.
Thus, an optical film laminate having a thin polarizing film formed on a thermoplastic resin substrate and having a maximum stretching ratio of 6.5 times was obtained. Here, "maximum stretch ratio" means: the stretching ratio of the laminate before breaking was confirmed separately, and a value lower than the stretching ratio by 0.2 was regarded as the "maximum stretching ratio".
Finally, the thermoplastic resin substrate was taken out as the substrate (1) by peeling from the obtained optical film laminate.
The substrate (1) used had a thickness of 40 μm and a front retardation R0 of 668nm.
