Description

本発明は、インクジェットプリンタに使用されるインク及び印字物に関する。   The present invention relates to ink and printed matter used in an ink jet printer.

ポリオレフィン樹脂など、表面の活性が極めて乏しい基材にマーキング(印字、印刷)をする場合、基材と印字した塗膜との密着性が低いため、印字した塗膜は、他の物体が接触した場合、擦れ等によって容易に剥れたり転写したりしてしまう。   When marking (printing, printing) a substrate with extremely low surface activity, such as polyolefin resin, because the adhesion between the substrate and the printed coating is low, the printed coating is in contact with other objects. In such a case, it is easily peeled off or transferred due to rubbing or the like.

特許文献1には、メルカプトポリジオルガノシロキサンコポリマー添加剤を含む剥離可能なインク組成物が開示されている。   Patent Document 1 discloses a peelable ink composition containing a mercaptopolydiorganosiloxane copolymer additive.

印字物の内部構造を示す断面模式図である。It is a cross-sectional schematic diagram which shows the internal structure of printed matter.

以下、本発明の実施形態を説明する。以下に述べる実施形態は、本発明を具体化した一例に過ぎず、本発明の技術的範囲を限定するものではない。   Embodiments of the present invention will be described below. Embodiment described below is only an example which actualized this invention, and does not limit the technical scope of this invention.

本明細書において「印字物」とは、ポリエチレンテレフタレート基板、PETボトル等に噴射したインクを乾燥することにより溶剤を除去し、固定したものをいう。一般に、ドット状に印字したものが多く、複数個のドットの集合体も含む。   In the present specification, “printed matter” refers to a product obtained by removing and fixing a solvent by drying ink jetted onto a polyethylene terephthalate substrate, a PET bottle or the like. In general, many are printed in the form of dots, including an aggregate of a plurality of dots.

1.インクの構成材料
インクの構成材料は、着色剤、樹脂、界面活性剤、添加剤及び溶剤である。これらをオーバーヘッドスターラー等により溶解し、撹拌混合した後、孔径0.25〜10μmのフィルタにて濾過することにより、インクジェットプリンタ用インクが得られる。
1. Ink constituent materials Ink constituent materials are colorants, resins, surfactants, additives and solvents. These are dissolved by an overhead stirrer and the like, stirred and mixed, and then filtered through a filter having a pore size of 0.25 to 10 μm to obtain an ink for an inkjet printer.

(1)溶剤
溶剤の主成分としては、ケトン系溶剤を用いる。例えば、アセトン、メチルエチルケトン(MEK)、メチルイソブチルケトン(MIBK)等が挙げられる。その他、酢酸エステル、プロピオン酸エステル、酪酸エステル、吉草酸エステルなどのカルボン酸エステル系溶剤、メタノール、エタノール、プロパノール、ブタノールなどのアルコール系溶剤、エーテル系溶剤又はグリコール系溶剤を加えても良い。
(1) Solvent A ketone solvent is used as the main component of the solvent. For example, acetone, methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK), etc. are mentioned. In addition, carboxylic acid ester solvents such as acetate, propionate, butyrate, and valerate, alcohol solvents such as methanol, ethanol, propanol, and butanol, ether solvents, and glycol solvents may be added.

(2)樹脂
樹脂は、溶剤に溶解し、かつ、界面活性剤である変性シリコーンの変性部と親和性が高い樹脂が好適である。例えば、アクリル樹脂、スチレン−アクリル樹脂、ポリエステル樹脂、塩素化ポリオレフィン樹脂等を用いる。ここで、アクリル樹脂は、アクリル酸、アクリル酸エステル、メタクリル酸又はメタクリル酸エステルから合成される単重合体樹脂及び共重合体樹脂を含む。スチレン−アクリル樹脂は、スチレン−アクリル共重合体樹脂及びスチレン−メタクリル共重合体樹脂を含む。ポリエステル樹脂は、ポリエチレンテレフタレート、ポリエチレンイソフタレート、ポリプロピレンテレフタレート、ポリプロピレンイソフタレート、ポリブチレンテレフタレート及びポリブチレンイソフタレートを含む。これらは、単独又は2種以上混合して用いてもよい。
(2) Resin The resin is preferably a resin that dissolves in a solvent and has a high affinity for the modified portion of the modified silicone that is a surfactant. For example, acrylic resin, styrene-acrylic resin, polyester resin, chlorinated polyolefin resin, or the like is used. Here, the acrylic resin includes a homopolymer resin and a copolymer resin synthesized from acrylic acid, acrylic ester, methacrylic acid or methacrylic ester. Styrene-acrylic resins include styrene-acrylic copolymer resins and styrene-methacrylic copolymer resins. Polyester resins include polyethylene terephthalate, polyethylene isophthalate, polypropylene terephthalate, polypropylene isophthalate, polybutylene terephthalate and polybutylene isophthalate. You may use these individually or in mixture of 2 or more types.

(3)界面活性剤
界面活性剤としては、下記化学式(1)で表される変性シリコーンが挙げられる。この変性シリコーンは、シリコーン(ポリジメチルシロキサン)の側鎖であるアルキル基(アルキル鎖)の一部が下記化学式(2)で表される官能基で変性されたものである。この官能基は、一級アミノ基(NH)と二級アミノ基(NH)がアルキル基(アルキル鎖)を介して結合している構造である。変性シリコーンの分子量は5,000〜10,000であり、下記化学式(1)において、yは(x+y)の1〜5%であり、a,bはそれぞれ、1〜5の整数であることが好ましい。
(3) Surfactant Examples of the surfactant include modified silicones represented by the following chemical formula (1). In this modified silicone, a part of an alkyl group (alkyl chain) which is a side chain of silicone (polydimethylsiloxane) is modified with a functional group represented by the following chemical formula (2). This functional group has a structure in which a primary amino group (NH 2 ) and a secondary amino group (NH) are bonded via an alkyl group (alkyl chain). The molecular weight of the modified silicone is 5,000 to 10,000. In the following chemical formula (1), y is 1 to 5% of (x + y), and a and b are integers of 1 to 5, respectively. preferable.

インクの乾燥に伴って、変性シリコーンが印字物の表面に集まる。これにより、印字物の表面エネルギーが低下する。そのため、印字物と接触体との相互作用が低減し、耐転写性及び耐擦性が向上する。   As the ink dries, the modified silicone collects on the surface of the printed matter. Thereby, the surface energy of the printed matter is lowered. For this reason, the interaction between the printed matter and the contact body is reduced, and the transfer resistance and abrasion resistance are improved.

変性シリコーンは、インクの0.1〜1質量%の量でインクに添加される。添加量が0.1質量%以上の場合、充分な耐転写性及び耐擦性が得られる。変性シリコーン中のジメチルシロキサンは、ケトン系溶媒に対して溶解性が低いが、添加量が1質量%以下の場合、着色剤や樹脂等の析出物が生じない。   The modified silicone is added to the ink in an amount of 0.1 to 1% by weight of the ink. When the addition amount is 0.1% by mass or more, sufficient transfer resistance and abrasion resistance can be obtained. Dimethylsiloxane in the modified silicone has low solubility in a ketone solvent, but when the addition amount is 1% by mass or less, precipitates such as colorants and resins do not occur.

80.0gのMEK中に、樹脂として平均分子量約10,000のスチレンアクリル樹脂を15.0g、染料としてsolvent black 34を5.0g加え、撹拌して溶解した後、上記化学式(1)で表される変性シリコーンA(式中、x=100、y=3、a=3、b=3)を0.1g添加し、溶解した。得られた液を孔径0.5μmのポリプロピレン製フィルタで濾過した。こうして本実施例のインクを調製した。   In 80.0 g of MEK, 15.0 g of styrene acrylic resin having an average molecular weight of about 10,000 as a resin and 5.0 g of solvent black 34 as a dye are added, dissolved by stirring, and expressed by the above chemical formula (1). 0.1 g of the modified silicone A (where x = 100, y = 3, a = 3, b = 3) was added and dissolved. The obtained liquid was filtered through a polypropylene filter having a pore size of 0.5 μm. Thus, the ink of this example was prepared.

調製したインクを帯電制御方式のインクジェットプリンタで吐出し、ポリエチレンテレフタレート基板にドット状の塗膜を形成した。以下の実施例及び比較例でもポリエチレンテレフタレート基板を用いた。印字後24時間経過した塗膜を観察したところ、直径380μm、平均膜厚1.3μmであった。   The prepared ink was discharged with a charge control type ink jet printer to form a dot-like coating film on a polyethylene terephthalate substrate. Polyethylene terephthalate substrates were also used in the following examples and comparative examples. When the coating film which had passed 24 hours after printing was observed, the diameter was 380 μm and the average film thickness was 1.3 μm.

また、塗膜を断面加工し、塗膜の空気界面近傍部及び塗膜のポリエチレンテレフタレート基板界面近傍部をX線光電子分光法で元素分析を行った。ここで、空気界面は、塗膜が空気に接触している面であり、基板界面は、基板と塗膜とが接触している面である。元素分析の結果、変性シリコーンAの濃度は、基板界面近傍部に比べて空気界面近傍部で高く、塗膜の空気界面近傍部における変性シリコーンAの濃度は約90質量%であった。   Further, the coating film was subjected to cross-section processing, and elemental analysis was performed by X-ray photoelectron spectroscopy on the air interface vicinity portion of the coating film and the polyethylene terephthalate substrate interface vicinity portion of the coating film. Here, the air interface is a surface where the coating film is in contact with air, and the substrate interface is a surface where the substrate and the coating film are in contact. As a result of elemental analysis, the concentration of the modified silicone A was higher in the vicinity of the air interface than in the vicinity of the substrate interface, and the concentration of the modified silicone A in the vicinity of the air interface of the coating film was about 90% by mass.

本明細書においては、空気界面近傍部は、塗膜の表面から深さ約1nmまでの領域とし、基板界面近傍部は、基板と塗膜との接触面(界面)から深さ約1nmまでの領域とした。   In this specification, the vicinity of the air interface is a region from the surface of the coating to a depth of about 1 nm, and the vicinity of the substrate interface is from the contact surface (interface) between the substrate and the coating to a depth of about 1 nm. The area.

図1は、印字物の断面を模式的に示したものである。   FIG. 1 schematically shows a cross section of a printed matter.

本図において、印字物100は、ポリエチレンテレフタレート基板200の表面に形成されている。印字物100が空気と接する面には、変性シリコーンが集まり、空気界面近傍部101を形成する。一方、ポリエチレンテレフタレート基板200に接する印字物100の基板界面近傍部102においては、変性シリコーンの濃度が空気界面近傍部101に比べて低くなる。   In this figure, the printed matter 100 is formed on the surface of a polyethylene terephthalate substrate 200. The modified silicone collects on the surface of the printed material 100 in contact with air, and forms an air interface vicinity portion 101. On the other hand, in the substrate interface vicinity portion 102 of the printed matter 100 in contact with the polyethylene terephthalate substrate 200, the concentration of the modified silicone is lower than that in the air interface vicinity portion 101.

なお、変性シリコーンの濃度は、次の方法で算出した。   The concentration of the modified silicone was calculated by the following method.

ドット状の塗膜と同様にして平均膜厚1.3μmの試料を作製し、XPS(X線光電子分光法)を用いてSi、O及びCの量を測定する。XPSは、試料のほぼ表面のシグナルを検知することから、それを空気界面近傍部のシグナルとみなす。   A sample having an average film thickness of 1.3 μm is prepared in the same manner as the dot-like coating film, and the amounts of Si, O, and C are measured using XPS (X-ray photoelectron spectroscopy). XPS detects a signal on the almost surface of the sample and considers it as a signal in the vicinity of the air interface.

また、試料を断面加工し、エネルギー分散型X線分析(EDX)で表面と内部との元素比を求める。   In addition, the sample is processed into a cross-section, and the elemental ratio between the surface and the inside is determined by energy dispersive X-ray analysis (EDX).

試料中の変性シリコーン及び樹脂に含まれるSi、O及びCの量は、分子構造から既知であるため、XPS及びEDXの両データから算出することができる。算出したSi、O及びCの量から空気界面近傍部における界面活性剤(変性シリコーン)の濃度を求める。   Since the amounts of Si, O and C contained in the modified silicone and resin in the sample are known from the molecular structure, they can be calculated from both XPS and EDX data. From the calculated amounts of Si, O and C, the concentration of the surfactant (modified silicone) in the vicinity of the air interface is determined.

実施例1のインクに塩素化ポリオレフィン樹脂を1.0g加えたインクを調製した。調製したインクについて、実施例1と同様に塗膜を観察したところ、直径380μm、平均膜厚1.3μmであった。   An ink was prepared by adding 1.0 g of chlorinated polyolefin resin to the ink of Example 1. For the prepared ink, the coating film was observed in the same manner as in Example 1. As a result, the diameter was 380 μm and the average film thickness was 1.3 μm.

また、実施例1と同様に塗膜の界面近傍部を元素分析したところ、基板界面近傍部に比べて空気界面近傍部の変性シリコーンAの濃度が高く、塗膜の空気界面近傍部における変性シリコーンAの濃度は約90質量%であった。   Further, elemental analysis of the vicinity of the interface of the coating film as in Example 1 reveals that the concentration of the modified silicone A in the vicinity of the air interface is higher than that in the vicinity of the interface of the substrate, and the modified silicone in the vicinity of the air interface of the coating film. The concentration of A was about 90% by mass.

実施例1のインクに塩素化ポリオレフィン樹脂を2.0g加えたインクを調製した。調製したインクについて、実施例1と同様に塗膜を観察したところ、直径380μm、平均膜厚1.3μmであった。   An ink was prepared by adding 2.0 g of chlorinated polyolefin resin to the ink of Example 1. For the prepared ink, the coating film was observed in the same manner as in Example 1. As a result, the diameter was 380 μm and the average film thickness was 1.3 μm.

また、実施例1と同様に塗膜の界面近傍部を元素分析したところ、基板界面近傍部に比べて空気界面近傍部の変性シリコーンAの濃度が高く、塗膜の空気界面近傍部における変性シリコーンAの濃度は約90質量%であった。   Further, elemental analysis of the vicinity of the interface of the coating film as in Example 1 reveals that the concentration of the modified silicone A in the vicinity of the air interface is higher than that in the vicinity of the interface of the substrate, and the modified silicone in the vicinity of the air interface of the coating film. The concentration of A was about 90% by mass.

実施例1のインクと染料の種類が異なり、塩素化ポリオレフィン樹脂を加えたインクを調製した。Solvent black 27を5.0g、塩素化ポリオレフィン樹脂を5.0g添加し、溶解した。調製したインクについて、実施例1と同様に塗膜を観察したところ、直径380μm、平均膜厚1.3μmであった。   The ink of Example 1 was different from the type of dye, and an ink added with a chlorinated polyolefin resin was prepared. 5.0 g of Solvent black 27 and 5.0 g of chlorinated polyolefin resin were added and dissolved. For the prepared ink, the coating film was observed in the same manner as in Example 1. As a result, the diameter was 380 μm and the average film thickness was 1.3 μm.

また、実施例1と同様に塗膜の界面近傍部を元素分析したところ、基板界面近傍部に比べて空気界面近傍部の変性シリコーンAの濃度が高く、塗膜の空気界面近傍部における変性シリコーンAの濃度は約90質量%であった。   Further, elemental analysis of the vicinity of the interface of the coating film as in Example 1 reveals that the concentration of the modified silicone A in the vicinity of the air interface is higher than that in the vicinity of the interface of the substrate, and the modified silicone in the vicinity of the air interface of the coating film.
